That was unexpected

Seems like if you click "Exit" in cssh it ends your entire desktop session. That doesn't seem like a good thing to me.

Also, when playing with the HFSC traffic shaper on a Debian server I managed to lock the system up 3 times (mostly when changing the maximum latency parameters). I think that indicates a pretty serious kernel bug, which is a shame because HFSC is by far the best Linux traffic shaper.
