Good to hear.
The concern of this patchset was early OOM kill with too many scanning.
I can throw such concern out from now on.

At least, I haven't been able to trigger a premature OOM.

AFAIR, Andrew had a premature OOM problem[1] but I couldn't track down at that time.
I think this patch series might solve his problem. Although it doesn't, it should not accelerate
his problem, at least.

Andrew, Could you test this patchset?

Gladly, but not until Wednesday most likely.  I'm defending my thesis
on Monday :)
