Steve Glanstein suggested to me that the password sniffer exposed
by Gene Gaunt be augmented with a little twist: if the user ID found
is that of the user running the sniffer, then blank out the user ID and
password in the buffer. Include this little program as one of your start-
up programs, and you have decreased the chance that someone
can sniff your password.

Both Steve and I have actually written such a program. It is possible
to run this at SECLVL 40 (it is in user state). A system-state version
would run under 50.
