I don't think that dt leaves processes running.  It just doesn't remove
the entries from /var/run/utmp (?) for the various jobs.

If you echo "" > /var/run/utmp you can reset your machine (of course,
the entru for your currently running session will be zapped too...)

The terminal was probably dubbed "insecure" (i.e., no root logins).
