please, could someone with a system where:
	$ ssh -t host
	% sleep 1234 &
	% exit
	$
hangs with openssh try whether rlogin hangs, too?

if rlogin does not hang, could you please check the source of rlogin
and try to figure out how it handles the filedescriptors that connect
rlogind to the shell. what happes with the filedescriptors after the
shell dies?

thanks, -m
