OK, good to hear that.

I agree that desktop users would probably prefer something even
more aggressive.  However, we do need to balance this against
other workloads, where inactive file pages need to be given a
fair chance to be referenced twice and promoted to the active
file list.

Because of that, I have chosen a patch with a minimal risk of
regressions on any workload.
