The patch aims to fix the situation where OOM triggers too late.

It might have some effect when pagedaemon cannot cope with the speed of
page allocations, but it would do it in rather rude manner of causing
OOM if some process cannot get a free page for long time because page
daemon does not provide enough free pages and other allocators steal
the limited supply.
