That would interest me too.

I made some very limited testing on Squeak 3.9.1 and the Mac VM, these
are my observations:

300 MB, hogs CPU badly, image grows dangerously but works
600 MB, hogs CPU badly, low space semaphore, image unusable
4 GB, Squeak image crashes, system unusable, reboot required
