A facility for determining whether to consistency-check a cache entry is
described. The facility randomly or pseudorandomly selects a value in a
range. If the selected value satisfies a predetermined
consistency-checking threshold within the range, the facility
consistency-checks the entry, and may decide to propagate this knowledge
to other cache managers. If, on the other hand, the selected value does
not satisfy the consistency-checking threshold, the facility determines
not to consistency-check the entry.
