[squeak-dev] Semaphore >> #terminateProcess

Hi, there.

Is there a way to change Semaphore >> #terminateProcess that it would also terminate a process that has not run yet? Shout's background styling can leave many processes behind, waiting for semaphores that have long been forgotten. Here is a minimal example, extracted from Shout:

| m s |
m := Monitor new.
s := nil.

1000 timesRepeat: [
m critical: [
s ifNotNil: [s terminateProcess. s := nil] ].

m critical: [
s := Semaphore new.
[s wait] fork.
Processor yield "Important!"].

s terminateProcess.


After this code snipped, shouldn't be any new processes waiting for those semaphores... "Processor yield" is really necessary here...
