The only things I know I've run lately tunneled are Mozilla-thunderbird 
and the vmware console.  In the past I've also run Firefox on a remote 
machine (although there's also some magic there where, if I remember 
right, it brought up the local machine's version of FF.)  I've also run 
Open Office.

Unless something is "automagically" monitoring in the background, I 
thought all of these were either independent or Gnome-based?

As an addendum to the forwarding message I sent just a few minutes ago, 
I do have port-forwarded sessions running in the background to redirect 
some mail often running, but not always when this happens and they're 
done on separate instances (machine A has 2 ssh forwarding sessions 
running and a third ssh that I'm using to console into another machine, 
and that third one is what may hang when I log out).
