No, the idea is that we stop paging one or more processes altogether
and suspend them for a while, flushing their entire resident set out
to disk for the duration. It's something very valuable when you are
running big concurrent batch jobs, and essentially moves the fairness
problem out of the memory space and into the scheduler, where we _can_
make a reasonable stab at being fair.
