hang on exit bug under Linux

[Nicolas Williams]

Sorry, Unix systems just work this way you know? RSH hangs the same
way if the remote command keeps stdio open. I learned to use rsh with
stdio redirection to /dev/null long before SSH became the norm.

So what's the problem then?

This topic and these arguments seem to be re-tread, over and over.

I'd like to see a client-side option to have the client end the primary
session as soon as the remote command is launched, with an optional
timer. But in the meantime, I know how to redirect stdio. And the
agent/x11/port forwarding hang bug supposedly is fixed (I can't test it
yet), so I'm pretty happy(*).

(*) I'd like a patch that applies cleanly to 2.9p2 for the
agent/x11/port forwarding hang bug. The one I found on the list does
not, in fact, apply.

Cheers,

Nico
