I believe the answer is that the prioritizing code doesn't actually work
as well as it is intended to.
A suggestion here, Kern: Since the Director already "preschedules"
upcoming jobs, could it not sort and queue them in order of priority at
that time?

Not really, no. I simply stagger job starts by a minute or more in
their Schedules. (Actually, all my jobs but one run at the same
priority; the remaining job is my Catalog backup, which starts both at a
lower priority AND an hour later to let the other jobs finish first.)

I believe that's a good read. I'd never spotted that myself; it's good
to have fresh eyes on the documentation at times.
