We really should integrate this _now_, with the twist
that pages which could form a larger buddy should be
immediately deallocated.

This can give us a cheap way to:
- create larger memory buddies
- remove some of the pressure on the buddy allocator
  (no need to grab that last 64 kB area when 25% of
  user pages are lazy reclaim)
