New description:

 Coderman reported back in August that if you try to change from a listener
 on 0.0.0.0 to a listener on a specific
 address, Tor will often fail, because it doesn't close the old listener
 until the new listener is open (in order
 to be undoable), but it can't open the new listener until the old one is
 closed.

 See or-talk/or-dev thread, "Server node stalls on unsuccessful socks
 listener change."

 It looks like we have two options:
  1) Disallow the 0.0.0.0 -> non 0.0.0.0 change.
  2) When transitioning from 0.0.0.0, accept that the transition will not
 be perfectly undoable.
