	This is great to know. The only difference besides the
fact it now works is that one sees a closed-connection message
like what you see when you ssh to another system and spawn a
shell because that seizes tty's also.

	It just hadn't occurred to me before that you don't
seize a tty on the remote system when you remotely run an ssh
