Documentation: Serve Lisp requests
The multiprocessing capabilities in the x86 versions of CMUCL allow it
to operate as a lisp server. This can be useful in a situation where
you wish to execute a number of small scripts, where the overhead of
launching a separate CMUCL instance would be penalizing. For a real
application you would have to take security considerations into

(setf mp::*idle-process* mp::*initial-process*)
(mp::start-lisp-connection-listener :port 6789 :password "Clara")
;;; now you can telnet in and do:
$telnet localhost 6789
Connected to localhost.
Escape character is '^]'.
Enter password: "Clara"

Craig Brozefsky has developed a prototype application called qcmu which generalizes
this technique. It allows users to obtain either a REPL or to execute a
script on a CMUCL server. qcmu uses a client-server protocol which
incorporates authentication mechanisms.
