} I have yet to look at the source (not at work box), but why are there
} two different functions to assign the local port, instead of just one?

There is only one, tcp_connect() calls in_pcbbind().  There are lots
of other places in the code that also call in_pcbbind(), but the call
in tcp_connect() is the one that does the trick for telnet.
