If you're not interested in their exit status and don't want
any synchronization on their exit you can create them in the
detached state (pthread_attr_setdetachstate()) or have them
call pthread_detach() after they're created.  Otherwise you
have to call pthread_join() to get their exit status and
have them fully exit.
