[K12OSN] zombies and orphans and slow-downs, oh my!

[Todd O'Bryan]

I'm using LTSP 5 on an Ubuntu server and I'm getting lots of zombie
processes. In addition, students seem to be restarting the clients
instead of logging out, so I'm getting a decent number of processes that
say they're sleeping, but are owned by students who aren't logged in at
the moment.

Anybody have a cron job or anything that might help clean things up?

Thanks,
Todd
