>Description:
Jails keep on stucking in the system after stopping them. As i have experienced it mostly occurs when i leave something in the jail when stopping them.
i use to start/stop jails the rc.d script. i go inside a running jail with ``jexec <id> /usr/local/bin/bash'' (so, a standard shell), and when i'm in, i stop the jail. after i leave the shell i still can see the jail listed with jls.
i was unable to find any utilities to purge these unused entries from the jail "registry".
i have tried to put back it's id to /var/run/<id file>, and invoke the /etc/rc.d/jail/stop script again, but it had no effect on them.

>How-To-Repeat:
1) start up a jail
2) using jexec, enter into it with a shell
3) stop the jail
4) leave the jail with the jexec shell
5) check it with jls, the jail will be still around
