>From looking at the code, it seems possible for pthread_exit and 
pthread_cancel to put something into _Unwind_Exception::exception_class (or 
private_1/private_2) that could allow an extension of your patch to match 
them as if by name. But I'm definitely not an expert on this, so I thought 
it'd be better to ask.
