The simplest method is to assign each user a specific (unique) port number
with the JBCPORTNO environment variable. That way they will own their own
command history.

Another way would be to have a login proc (or some login script) that
removes the '$JBCRELEASEDIR/tmp/jutil_ctrl' record associated with the port
number the user obtains when the user logs in.
