I don't believe there's any useful generalization here, since job
runtimes probably differ by at least three orders of magnitude.

one one cluster where jobs often run for weeks (and are big-parallel),
our wait times can sometimes be weeks. on another, a serial farm,
throughput is often ~100 jobs/day, and wait times are much, much lower.
I find that users are happy if there's a general queue (which is
mostly FIFO, perhaps modulated by fairshare) *AND* a test queue
(for time-limited test jobs, such as debugging.)
