McBoaty : memory release

[MaraScott]

Right I hit a serious glitch. Python is not releasing memory between generations, so do a few in a row and the whole system goes down. The vae stuff and the node data needs to be cached to disk not held in system memory.

WAS Node Suite

inspire has some cache nodes, for once

Issue

when i hit queue, i get a out of memory error. then i hit just again queue, and it de-caches all kinds of stuff from before and the workflow goes on.
