Using the Harlequin lisp distribution, you can create a stream between two
computers using accept-tcp-stream-connection and connect-to-tcp-stream.
Now, is there any way to close and remove that stream once you are done
with it so that the port accepting the connection is either unbinded or is
free to connect with a different computer? The function close merely
closes the stream for input and doesn't get rid of the stream, it's just
unusable since it seems that you can't re-open it. Any future outside
connections to the accepting port are on a different stream. There is a
way to have only open stream existing at a port at a time or a way to have
more than one accpeting stream at a given port (without getting an
address is already in use error)?
