<p>I'm curious whether this could or should be fixed in the VM. Interrupt still works ... Any thoughts?</p>

Fix a bug: assigning suspendedContext := nil to a runnable but not active process would freeze the image when self is awakened. This can easily happen when a process gets preempted between the assignment and the next send.<br>
<br>
Try to execute this:<br>
p := [] newProcess resume. "p placed in run queue"<br>
p suspendedContext: nil. "image freezes"<br>
<br>
