Just to be sure that we are wasting enough time, you might want to make that

     100 timesRepeat: [1000!]

But assuming that makes no difference:

So that's the issue. Squeak and Pharo rotate the order of processes at a 
given priority whenever one is interrupted by a higher priority process. 
VAST appears not to do that (or there are no higher priority process 
running...). IOW,

Squeak and Pharo offer a Poor Man's Time Slicing, although with no 
guarantee that the slices are equal in width.
VAST offers what seems to ensure a process will not be pre-empted by 
another process at the same priority (which has a certain logical appeal 
;-) ).

Not having access to VAST, I can't tell you if this difference is 
accidental or intentional. Perhaps someone know a bit more...
