If I download latest and greatest moose image and latest and greatest VM for linux, I evaluate this code:

nil asParser star parse: 'b'

That leads to an infinite loop and I terminate after a few seconds using ctrl + . my image grows to approximately 500MB.

The problem is, if I close all the windows, call Smalltalk garbageCollect as many times as I want, the image is still 500MB (or 1.2GB in my real-case scenario). 

Cheers,
Jan
