I tried setting the KeepAlive parameter to no in /etc/sshd_config, then
restarting sshd.  I then opened an SSH session and left it idle.  Almost
exactly two hours later I noticed that it was disconnected with a comment
something like "read failed" and "connection reset by peer" -- I'm no
longer at my work computer, so I'm writing from memory.

So, turning off KEEPALIVE (or MAKEDEAD) seemed to have no effect.
