Smalltalk is preemptible, it is not time sharing.  Smalltalk processes 
run until they yield, ahve finished their work, or until a 
higher-priority waiting process is woken up by a signal on a semaphore.

In other words, semaphores (which means Delays and I/O events too) will 
preempt a process if lower priority processes are running.

It does indeed.

This would enable time sharing.
