Ok. Part of my confusion was that I thought BLooper deletes all attached
BHandlers, but that's not the case. So at least the pointer won't go stale.
I think I can fix my problem by constructing a BMessenger and check the
return value of SendMessage(). If that fails, I know I have to delete the
BHandler myself. The problem is here also that I cannot lock the BLooper,
or I will risk a deadlock.
