Concurrent alternatives to make map/filter/foreach using bordeaux-threads.

The functions spawn workers that consume items from a list or queue as soon as they are ready for one.

git clone https://github.com/garlic0x1/fusillade.git ~/quicklisp/local-projects/fusillade

The usage is what you expect, but with an extra first argument to specify the number of threads to use.

(ql:quickload :fusillade)
(use-package :fusillade)

(wmap 4 #'sleep '(1 2 2 2))     ; takes 2 seconds
(wforeach 2 #'sleep '(1 2 2 2)) ; takes 4 seconds
(wfilter 2 #'evenp '(1 2 2 2))  ; instant (no sleep)

Since this uses native threads, it is not ideal for heavy IO applications. Perhaps I will add async functions in the future.

Tests are incomplete.
