Here's the promised sysctl to dump a node's pagecache.  Please review!

This patch depends on the zone reclaim atomic ops cleanup:
http://marc.theaimsgroup.com/?l=linux-mm&m=112307646306476&w=2

Doesn't numactl --bind=node memhog nodesize-someslack do the same?

It just might kick in the oom killer if someslack is too small
or someone has unfreeable data there. But then there should be 
already an sysctl to turn that one off.

Doesn't the memhog hack also cause the machine to swap a lot?  The

Hack? - compared to your "solutions" it looks very clean to me.

zone_reclaim() path doesn't let the memory reclaim code swap.

reclaim with bound policy should only swap on the bound nodemask
(or at least it did when I originally implemented NUMA policy)
