I've a tendancy to leave myself logged in a time or two on the console,
then go and do real work on an Xterm somewhere else.  The problem with this
is that incoming talk requests go to the first matching utmp entry, usually
the console vtys, and I usually miss them.

Here is a patch to talkd which makes it send the request to the tty with
the lowest idle time.
