If I remember correctly, pthreads says that if the main thread exits while
other threads  are running then the process exits whether they like it or
not. I don't see this as being a
big problem although it would be nice if a thread could be told, so that it
could clean up.
( not all resources are cleaned up when a process terminates. )

Could the exception that caused a thread to die not be stored in the thread
class? That
would allow detection if it was desired.
