a page will not be reclaimed if the system is already at or below
the "min" threshold for that type of data.

a page will not be reclaimed if the system is already at or over
the "max" threshold for a different type of data.


the effect is that usage for a given type of data can exceed its max
as long as there is insufficient demand for other types of data.
but if demand for other types of data increases, pages of types
over their max will be reclaimed in preference to pages of types
not over their max.  if usage for all types is between their mins
and maxes then all pageable pages are eligible for reuse.
