Re: x forwarding over SSH

I notice that on Windows, Firefox lingers for a few moments after the
window is closed, presumably for garbage collection until the process
finally dies off.

Perhaps this is what's happening with you? Does it happen with other
applications, or just with Firefox?

Hi,

I am using SSH to do X forwarding and saw an interesting problem:  for
some applications, even when I closed the application itself, the SSH
session is still not closed.  For other applications, SSH sessions
closed whenever I closed the application.

For example, if I do:

ssh -X <host> xclock

then I close the xclock app, the ssh session exits.

but if I do:

ssh -X <host> firefox

then I close the firefox app,  the ssh session does not exit.

In the latter case, I can see the corresponding sshd process is still
running at <host>.  Is such behavior caused by the application?  any
insights are appreciated.

my SSH version is:
OpenSSH_5.1p1 Debian-6ubuntu2, OpenSSL 0.9.8g
