Right, we would need either UNIX-domain or TCP sockets for server
connections to work at all.

We require UDP packet loopback to work for the stats collector to work.
If it weren't working, certain regression tests would probably fail,
and definitely the "stats" test would fail. Richard's last message
shows that as having passed.
So I think his kernel must have more networking ability than he
supposes.
