I strongly suspect that the condition I'm dealing with (not being able
to restart the container) is an artifact of the devtmpfs kludge.  I'm
seeing some errors relating to /dev/loop* busy that seems to be related
to the hung resources resulting in the inability to remove the zombie
container.  Disregard until I can get further information following a
switch to a template based setup.
