APAR Error Description / Circumvention

-----------------------------------------------
A transaction count and an operation count are not being
atomically updated.  This can cause the counts to be incorrect.
As a result, an ASP quiesce may delay longer than necessary
before proceeding to its next quiesce step.

CORRECTION FOR APAR MA41833 :
-----------------------------
An "atomic" attribute is being assigned to the variables so that
the compiler generates code that prevents the incorrect result.

CIRCUMVENTION FOR APAR MA41833 :
--------------------------------
None.
