Well, they're good: our Torque-Maui tandem now responds even more
quickly and the percentage for periods of slow responses from Torque

loaded with I/O-intensive tasks, so we see this improvement. For more
responsive pbs_moms the problem I am fighting with shouldn't come up.

No regressions with something like 10k+ jobs per day.

Yes, as I said periods of irresponsiveness dropped by 7 times at our
I wonder if people from SuperCluster can review my patch.
