Hi all,


When I do this

	rsh roke -n 'sleep 100 >/dev/null >[2=1] &'

the rsh doesn't return immediately, as I would have expected.
It looks like file descriptor 6 is open on the other end, 
preventing rshd from exiting.  Is this an rc-ism?  Is there a
preferred idiom for closing all unwanted descriptors?
