Wait, all delays are signaled when the image is saved? So, if I have a five minute delay in a process and I save the image 2 seconds later...

[ d := 5 minutes asDelay.
d wait.
Transcript logCr: 'asd' ] fork.

Smalltalk snapshot: true andQuit: false.

That is a limitation but is also a bug :/...�

if Delay could implement #copy, then you could write like:


delay := 1 seconds asDelay.
10 timesRepeat: [ [ delay copy wait ] fork ].

this is because a Delay has 1:1 correspondence with its semaphore object.
and when you scheduling it multiple times, it will end up using same
semaphore for all instances of it...
and that's why you get weird behavior.
