	Are you using MSWindows? When using MSWindows, the close() to
	socket object actually makes a winsock shutdown(2) call.  The
	socket is destroyed (by calling winsock close()) when the
	application exits.  Most MS TCP implementations simply destroy
	the TCP PCB and discard the buffered unsent data when the socket
	is destroyed.  SO_LINGER, as mentioned by another poster, may
	help.
