It's not really anything that is going to get in the way of zoned
allocation: the two principles are orthogonal. If we are zoning in
blocks of 32k or larger, then the zoning itself is not telling us
anything about smaller units than that. Page colouring and CPU hot
lists work best at the smallest granularity available, i.e. on a
per-page basis.
