not true for user-defined job priorities (what we're talking about in
this thread).  the schedd will never preempt a job because of these
priority values, so you don't have to worry about that.  user
priorities (the fair-share stuff enforced by the negotiator, which you
can view/manage via condor_userprio) can cause preemption (if the
PREEMPTION_REQUIREMENTS expression evaluates to true), but job
priorities never do.
