If you set the socket option SO_REUSEADDR, you can reopen a socket that is stuck
in TIME_WAIT. There are a few things that you should know about doing that,
namely with regard to stale packets destined for the old process that make it
instead to the new process. "UNIX Network Programming" by W. Richard Stevens
(ISBN 0-13-490012-X) has some excellent information about this, and pretty much
everything else you need to know about socket programming.
Check the man pages for getsockopt(2) and setsockopt(2).
