When looping over the current list of sockets we are connected to,
use getpeername() not getsockname() to find out who the remote
end is. This change avoids spurious close() and (rare) failure.
Origin: ISC bug #18625 and fixed in libbind 6.0

TCP isn't supported on some dns servers, which makes the old code
hang forever.
NOT adding a stopship to remove debugging stuff - it was too painful
(14s timeout on failed tcp dns lookups) so we decided not to bother people.
