APAR Error Description / Circumvention

-----------------------------------------------
On very large machines it is possible that we will calculate the
reserved storage for a pool incorrectly.  The current algorithm
sums counts that are kept in every subpool of the memory pool,
and does not hold any locks, so if the counts are changing it is
possible to load a stale or incorrect count.

CORRECTION FOR APAR MA44753 :
-----------------------------
Instead of using this volatile count, we will use a count that
doesn't change as often, thus eliminating the problem.

CIRCUMVENTION FOR APAR MA44753 :
--------------------------------
None.
