I don't think the loopback optimization is really necessary.
And in any event, RTCF_LOCAL doesn't necessarily mean that
the connection doesn't go "on the wire" especially when using
Julian's "send to self" patch which I might add at some point.
Anyways, please resend to me the version without the loopback
hack and I'll add it to my 2.6.11 queue.
Thanks Stephen and Michael.
