But isn't this effectively (although maybe indirectly) just measured by
cache hit rate? If you increase the cache size and the hit rate
increases, then stuff must have been getting pushed out before it expired.
But if you increase cache size and the hit rate stays about the same, then
likely things are expiring before they get pushed out.
