I rearranged again to make the output self explanatory...
| coll count sem |
Transcript clear; show: 'count' ; tab

Transcript output logic is wicked, flush or not. Especially if you Halt now.
Check for stepGlobal senders and implmenters and see it in all its glory
with flags and all.
You can then understand why things are weird.
Some World doOneCycle peppered around may confuse things a bit more.
Use a log
Hi Vince,
some of your problem may be in the Transcript buffering some of its output. It
is best to add a ; flush to the end of all your printing, e.g. Transcript show:
'waiting...'; cr ; flush.

Hello
I am playing around with Semaphore, and wrote the following:
| coll count sem |
coll := Array withAll: (1 to: 100).
count := 0.
sem := Semaphore new.
coll do: [ :each |
count := count + 1.
(count >= 5)
ifTrue: [
Transcript show: 'waiting...'; cr.
sem
