I'm not sure what the reason for the stale processes is, but I recall
reading on the debian-edu lists that people were writing workaround scripts
for clearing out old processes some months back.  A quick search gives me:

	http://www.skolelinux.no/~klaus/newnotater/x4181.html

which assumes you are using KDM in that he suggests you hook it into
/etc/kde2/kdm/Xreset.  As edubuntu doesn't use KDM, I suppose you could
possibly put it in /etc/X11/Xsession or even in the ssh_remote_command
variable in /opt/ltsp/i386/usr/sbin/ldm.

It also seems to presume nobody is logged in in two places (which they
probably shouldn't anyway).
