Comment (by yawning):

 Replying to [comment:10 nickm]:
 > I think we should have Tor exit if we have no loopback interface.

 Doesn't that totally break OpenVZ and FreeBSD jails?  I think that's a bit
 extreme.  We certainly should fail closed if the user automatically
 configures certain ports that have no business of being public, but Tor
 should continue to function jammed into a jail assuming it uses an
 `AF_UNIX` ControlPort for example...
