Hi,

I hope this patch will alleviate some of Andrea's
problems with the page cache growing out of bounds.

It makes sure that, when the cache uses too much,
shrink_mmap() is called continuously; only the
last thing tried can be something else.

I'd like to hear some results, as I haven't tried
it myself ... It seems obvious enough, so it would
probably be best if it's tried ASAP with as many
different machines/loads as possible.

Rik.
