I don't know if this is the case, but I can see why this happens: 
terminating is not something that happens instantaneously when you send 
#terminate.  In particular, it could take a while if p has a low priority.

I don't remember offhand is Squeak has a #primTerminate method, or 
something like that, that is basically

     suspendedContext := nil.
     self suspend

If it has, allowing to resume after a #primTerminate would definitely be 
a bug.
