Hi.

This is a follow-up to
https://github.com/openssh/openssh-portable/pull/9

I've tried what happens when I set
ForwardX11Timeout=0(s|w|m...)

It seems that after having logged into a session, one can not longer
start any X client (or better said, the program starts, but it cannot
connect to the X server on the local end of my ssh).

But apparently something like
ssh host xman
still works. So I've expected that it would mean "direct execution of
an X client allows it's connection".

So I've tried
echo "xman &" | ssh host
which I've expected to be just like normal session login,... but
"immediately" starting the client... thus I guess it wouldn't
work.
However, it also allows connection.


So what exactly is ForwardX11Timeout=0?
I can adapt my pull request to include this information, once I have
it.


Cheers,
Chris.
