Actually, this is worthwhile to think about. We already have some unwind 
protection primitives and it seems quite all right to me to have another 
"marker primitive" that could be evaluated upon termination. As a matter 
of fact, we might redefine #ifCurtailed: to take an optional argument 
which gets to see the suspendingList (or the entire process). Something 
along the lines of:

   [self wait] ifCurtailed:[:list|
     list == self ifTrue:[caught := false].
   ].

At which point all the VM needs to do is to take the process primitively 
#offList which we need anyways.
