That shouldn't be possible at all.  You cannot have multiple
processes listen on the same address and port, no matter
whether they're in a jail or not.

If this patch for multiple IP numbers in jails breaks that
behaviour, then it does not fix INADDR_ANY behaviour, despite
what the subject says.  :-)

That last command _must_ fail with errno EADDRINUSE.
