sending signals could be dangerous, depending on the permissions
of the sending process, e.g. a root-owned sshd sending to
a setuid process. but i'm not sure. we had similar code there before.

Maybe I'm being thick but I don't see 
how this could be dangerous (or, at 
least, any more dangerous than the 
SIGHUP it would get anyway if it had a 
pty).

hm, i'm not sure, but it might behave different if it had a pty. but
perhaps i'm mixing up things.

in any case, the kill should be done from within session.c
on session cleanup, i think.

Just for comparision, the man page for 'rsh' states:

"Interrupt, quit and terminate signals  are  propagated  to
 the  remote  command;"

It seems reasonable to me for ssh to behave like rsh in this respect.
