>Description:
Jails stopped via /etc/rc.d/jail are not going away from jls output (waited several hours).


JID  IP Address      Hostname                      Path
  1  10.0.90.3       notebook.multiverse.local     /zfsjails/notebook



No jailed processes are running:

# ps aux | grep J
root  1944  0.0  0.1  5888  1240  p0  R+    3:35AM   0:00.00 grep J
>How-To-Repeat:
Configuring jails:.
Starting jails: lab.multiverse.local. [UFS-backed jail]

# jls
JID  IP Address      Hostname                      Path
  2  10.0.90.2       lab.multiverse.local          /ufsjails/lab
  1  10.0.90.3       notebook.multiverse.local     /zfsjails/notebook

# /etc/rc.d/jail stop lab
Stopping jails: lab.multiverse.local.

# jls
   JID  IP Address      Hostname                      Path
     1  10.0.90.3       notebook.multiverse.local     /zfsjails/notebook


UFS-backed "lab" jail vanished as expected, ZFS-backed "notebook" jail remains, even after being stopped.
