[K12OSN] Kill User processes on log-off

[Brandon Kovach]

It's my understanding that there are issues in Linux with being logged 
in as the same user in multiple instances.  Is this not correct?  There 
are howtos on the k12 page about how to disallow multiple instances of 
the same login.  I set those up here at my school and things are much 
smoother now.  We had problems with users losing the ability to run 
Ooffice or losing documents that they were working on.  Although we 
occasionally still have a machine freeze (working on that one), we 
haven't had the Ooffice problem or missing documents since.
