Yes, that is exactly the problem. B will simply become unreferenced when C
stops. That is if A doesn't hold a reference. BUT: If A holds a reference (and
will therefor delete the object when it goes out of scope) you are in much
deeper trouble, because then you might kill B while it is still running in C's
context.
BTW: I created a template to run a given object in its own thread and also
delete it after the event-loop finished. Interested?
