This is not at all surprising; your code performs a very complex calculation
which will take quite a while to run. Since it runs at user priority, no
process at the same or lower priority will get any slot to run.
You could:-
a) put a 'Processor yield' somewhere in the outer loop, or
b) startup a higher priority process that simply loops around waiting for 'x'
milliseconds and which ought to stir-up the process lists a bit. This depends
on details of the process suspend/resume implementation.
I'd give a) a try first because it is so much simpler.
Change
1.0 to: 300.0 do: [:i | 1.0 to: 150.0 do:
to
1.0 to: 300.0 do: [:i | Processor yield.
1.0 to: 150.0 do:
and see if it helps.
