There's nothing really to fix, so why wait for patches?

Actually, now I'm convinced that even having the sshd send SIGHUP to the
process group when the session leader exits might not be correct.

Is it possible to have the client, upon reception of the session exit
message, choose to send SIGHUP to the session (meaning the process
group) and/or force the channels closed? Is this at all possible in the
SSHv2 protocol?

If so then that could be a client side option. That would shut up most
folk.

But definitely you guys need an FAQ...

Cheers,

Nico
