Yes, I'll add a call to getsockname after bind if the port number is 0
and patch the actual port number into the process-contact list.

Hmm, yes, that is a good question.
Referring to my recent answer to Alex on emacs-devel, I guess the
"clean" approach to this problem is to just add a 9th argument,
SERVER, to open-network-connection rather than overloading the
HOST argument ...
