This is probably a safer version. It works for me.
semA := Semaphore new.
semB := Semaphore new.
thread1 := [Transcript cr; nextPutAll: 'b1'. semB signal. semA wait.
Transcript cr; nextPutAll: 'b2'. ] fork.
thread2 := [Transcript cr; nextPutAll: 'a1'. semA signal. semB wait.
Transcript cr; nextPutAll: 'a2'.] fork.
[thread1 isTerminated and: [thread2 isTerminated]] whileFalse:
[(Delay forMilliseconds: 100) wait].
Transcript flush
Now to move on to another pattern.
