ah.  This looks good.  I'll find a hunk of time to go through this work
and through Paul's patches.  It'd be good to get both patchsets lined
up in -mm within a couple of weeks.  But..

We need to decide whether we want to do per-container memory limitation via
these data structures, or whether we do it via a physical scan of some
software zone, possibly based on Mel's patches.
