In recent images, SqueakJS often does not allow proper debugging, most of
the buttons are disabled, e.g. just executing "self halt" in a workspace:
self interruptedProcessIsReady => false
interruptedProcess isSuspended => false
myList isNil => false
If, instead of sending #halt I do a "debug it", it works fine. In that
case, "myList" is nil and interruptedProcessIsReady answers true.
Does anyone have a clue what the difference might be?
