[K12OSN] Kill User processes on log-off

[Daniel Hedblom]

I dont know if thats such a good idea, what if i want to login from two places
at once? The user ps should be killed at logout or at disconnected session,
killing them at login is, well, backwards. The same issue is making linux look
unstable if i use it at a normal desktop extensively under longer periods. I
have seen this behaviour on Gentoo, Redhat FC1, 2 and 3 and Ubuntu Linux. The
common dominator is that i have used GDM on them all.

Why the processes wont die i dont know but i suspect that they are just left
hanging totally unwitting the state of the session. 

Maybe i should just shut up and get my behind on track learning programming.
