Subj : pthreads: cancelling thread blocked on berkeley socket accept()

I have a thread running on a listen()->accept()->spawn_job()->listen() 
loop on a socket (unix/berkeley). I have the socket set to block on the 
accept(). spawn_job() dispatches a thread to handle the incoming request.

When the application is shut down, I want to cancel the thread and 
close() the socket. Is it appropriate to call pthread_cancel() on a 
blocked thread? If I call pthread_cancel(listener) and then 
pthread_join(listener) from the main (parent) thread, am I guaranteed 
that it is safe to close() the socket?

Thanks in advance,
Luke
