actually...it has nothing to do with x.  it's more like, ip.  ip looks
up the route for the specified destination and for local addresses,
this will correspond to the loopback interface.  the packet'll just
get looped back and no wires will ever be involved.  you can actually
see this by tcpdump-ing your lo0 interface and noticing all the
packets that *don't* have 127.0.0.1 as the source or dest address.
