No question, so not that scenario.

Possibly killed, (possibly run out of /tmp space or disk space in
general, benign DOS attack, etc.), and it depends on what kind of risk
you are willing to take with your clients data while the batch process
is sharing the machine with them and vice versa.  Or to put it another
way, who in your group is willing to have a batch process run the
background on their systems idle cycles while they are working on their
own projects?  If you have racks of unused old Sun's and SGI's and want
to make a new cluster without clients I think this is a different
