 This matter is complicated by needing different solutions for different dask scheduler
 types, i.e. local 'threads' scheduler, local 'processes' or distributed.
 
+In any case, a "iris.fileformats.netcdf.saver.Saver" object contains a netCDF4.Dataset
+targetting an output file, and creates a Saver.lock object to serialise write-accesses
+to the file from dask tasks :  All dask-task file writes go via a
+"iris.fileformats.netcdf.saver.DeferredSaveWrapper" object, which also contains a link
+to the Saver.lock, and uses it to prevent workers from fouling each other.
+For each chunk written, the DeferredSaveWrapper acquires the common per-file lock;
+opens a Dataset on the file; performs a write to the relevant variable; closes the
+Dataset and then releases the lock.
+
+For a threaded scheduler, the Saver.lock is a simple threading.Lock().  The workers
+(threads) execute tasks which contain a DeferredSaveWrapper, as above.  All of those
+contain the common lock, and this is simply **the same object** for all workers, since
+they share an address space.
+
+For a distributed scheduler, the Saver.lock is a `distributed.Lock()` which is
+identified with the output filepath.  This is distributed to the workers by
+serialising the task function arguments, which will include the DeferredSaveWrapper.
+A worker behaves like a process, though it may execute on a remote machine.  When a
+distributed.Lock is deserialised to reconstruct the worker task, this creates an object
+that communicates with the scheduler.  These objects behave as a single common lock,
+as they all have the same string 'identity', so the scheduler implements inter-process
+communication so that the mutally exclude each other.
+
+It is also *conceivable* that multiple processes could write to the same file in
+parallel, if the operating system supports it.  However, this also requires that the
+libnetcdf C library is built with parallel access option, which is not common.
+With the "ordinary" libnetcdf build, a process which attempts to rpen for writing a file
+which is _already_ open for writing simply raises an access error.
+In any case, Iris netcdf saver will not support this mode of operation, at present.
+
+We don't currently support a local "processes" type scheduler.  If we did, the
+behaviour should be very similar to a distributed scheduler.  It would need to use some
+other serialisable shared-lock solution in place of 'distributed.Lock', which requires
+a distributed scheduler to function.

 🚀 Performance Enhancements
 ===========================
 
-#. N/A
+#. `@pp-mo`_ changed the netCDF loader to fetch data immediately from small netCDF
+   variables, instead of creating a dask array: This saves both time and memory.
+   Note that some cubes, coordinates etc loaded from netCDF will now have real data
+   where previously it was lazy.  (:pull:`5229`)

* cube and io lazy data notes added

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Added comments within analysis, as well as palette and iterate, and what's new

* fixed docstrings as requested in @trexfeathers review

* reverted cube.py for time being

* fixed flake8 issue

* Lazy data second batch

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

+   cell with the bottom left bound in the cell to its right, and the top left bound
+   in a cell with the bottom left bound in the cell above it. Now all bounds are
+   compared with all adjacent bounds from neighbouring cells. This affects
+   :meth:`~iris.coords.Coord.is_contiguous` and :func:`iris.util.find_discontiguities`
+   where additional discontiguities may be detected which previously were not.

The extent of hygroscopic growth depends on the relative humidity and the composition of the particles.

       <description>Isotopic enrichment of 14C, often called d14C or delta14C (lower case delta), is used to calculate the fossil fuel contribution to atmospheric carbon dioxide using isotopic ratios of carbon. It is a parameterisation of the 14C/12C isotopic ratio in the sample with respect to the isotopic ratio in a reference standard. It is computed using the formula (((14C/12C)sample / (14C/12C)standard) - 1) * 1000. The quantity called D14C, or Delta14C (upper case delta) is d14C corrected for isotopic fractionation using the 13C/12C ratio as follows: D14C = d14C - 2(dC13 + 25)(1+d14C/1000). If the sample is enriched in 14C relative to the standard, then the data value is positive. Reference: Stuiver, M. and H.A. Polach, 1977, Discussion reporting of 14C data, Radiocarbon, Volume 19, No. 3, 355-363, doi: 10.1017/S0033822200003672. The reference standard used in the calculation of delta14C should be specified by attaching a long_name attribute to the data variable. &quot;C&quot; means the element carbon and &quot;14C&quot; is the radioactive isotope &quot;carbon-14&quot;, having six protons and eight neutrons and used in radiocarbon dating.</description>

Chlorophylls are the green pigments found in most plants, algae and cyanobacteria; their presence is essential for photosynthesis to take place. There are several different forms of chlorophyll that occur naturally. All contain a chlorin ring (chemical formula C20H16N4) which gives the green pigment and a side chain whose structure varies. The naturally occurring forms of chlorophyll contain between 35 and 55 carbon atoms. The chemical formula of chlorophyll c3 is C36H44MgN4O7.

       <description>Mass concentration means mass per unit volume and is used in the construction mass_concentration_of_X_in_Y, where X is a material constituent of Y.  A chemical species denoted by X may be described by a single term such as &#39;nitrogen&#39; or a phrase such as &#39;nox_expressed_as_nitrogen&#39;. &quot;Noy&quot; describes a family of chemical species. The family usually includes atomic nitrogen (N), nitrogen monoxide (NO), nitrogen dioxide (NO2), dinitrogen pentoxide (N2O5), nitric acid (HNO3), peroxynitric acid (HNO4), bromine nitrate (BrONO2) , chlorine nitrate (ClONO2) and organic nitrates (most notably peroxyacetyl nitrate, sometimes referred to as PAN, (CH3COO2NO2)). The list of individual species that are included in a quantity having a group chemical standard name can vary between models.  Where possible, the data variable should be accompanied by a complete description of the species represented, for example, by using a comment attribute. The phrase &#39;expressed_as&#39; is used in the construction A_expressed_as_B, where B is a chemical constituent of A. It means that the quantity indicated by the standard name is calculated solely with respect to the B contained in A, neglecting all other chemical constituents of A.</description>

+      <description>In thermodynamics and fluid mechanics, stagnation temperature is the temperature at a stagnation point in a fluid flow. At a stagnation point the speed of the fluid is zero and all of the kinetic energy has been converted to internal energy and is added to the local static enthalpy. In both compressible and incompressible fluid flow, the stagnation temperature is equal to the total temperature at all points on the streamline leading to the stagnation point. In aviation, stagnation temperature is known as total air temperature and is measured by a temperature probe mounted on the surface of the aircraft. The probe is designed to bring the air to rest relative to the aircraft. As the air is brought to rest, kinetic energy is converted to internal energy. The air is compressed and experiences an adiabatic increase in temperature. Therefore, total air temperature is higher than the static (or ambient) air temperature. Total air temperature is an essential input to an air data computer in order to enable computation of static air temperature and hence true airspeed.</description>

+Unit tests for the :mod:`iris.fileformats.netcdf._dask_locks` package.
+
+Note: these integration tests replace any unit testing of this module, due to its total
+dependence on Dask, and even on Dask's implemenetation details rather than supported
+and documented API and behaviour.
+So (a) it is essential to check the module's behaviour against actual Dask operation,
+and (b) mock-ist testing of the implementation code in isolation would not add anything
+of much value.
