The port can't be used because it's still in use.  When you
close a TCP connection, it doesn't go away immediately.  It
goes into a "wait" state for several minutes just in case there
are packets belonging to that connection wandering around the
internet.  If you want to skip that waiting state (a decision
which a small risk associated), set the SO_REUSEADDR option on
the socket.
