After more thought, I've come to the conclusion that it's not easy to do
away with the lport hash, and that changes would only benefit certain
applications.  So, I've given up on the lport reuse issue and refocused on
the problem of time_wait sockets clogging up all local ports under certain
situations.  I did manage to find a good solution for that problem, and
it'll be committed pretty soon.
