I've noticed the same timeout behavior as well, but only when connected from
outside the local network.  ssh connections between machines on the local
network stay connected until I terminate them.  However, when I connect from
a remote network, the connection does get dropped after some amount of time.
However, when this happened, I did not have any spare time to investigate, so
I can't offer any further information at this time.

FWIW, my ssh server is OpenBSD 2.6 with OpenSSH-1.2 while both ssh clients
(local and remote) are Linux 2.2.x with OpenSSH-1.2.2.
