Actually, the first allocation loop in __alloc_pages()
is testing against zone->pages_high and allocating only
from zones which have MORE than this.
So I guess this should only result in a somewhat slower
and/or softer fallback and definately worth a try.
Oh, and we definately need to un-lazy the queue movement
from the inactive_clean list. Having all of the pages you
counted on as being reclaimable referenced is a very bad
surprise ...

Rik
