/usr/bin/lock can be used to lock a terminal much like xlock does
for your X-windows session. Problem is, /usr/bin/lock cannot lock
your terminal indefinately. Rather you must specify a timeout
value, after which, your terminal is unlocked and become unsecured.
I have added a ``-n'' no timeout option to /usr/bin/lock
Currently the only way to get this functionality is to use a huge
timeout value and hope it is long enought (in time). This method
also requires you to know the maxium number of minutes you are
allowed to specify.

automagically. -lfoo has to be right to work, but ${LIBFO0} is too
easy to forget or misspell; nothing checks it and it should be
different for shared libraries.
