      Description

      The current way an application thread contributes to eviction when the cache is full can be unfair. Each thread will evict up to 10 pages, if a thread keeps failing to evict (for whatever reason) it will keep waiting.

      It makes more sense to track global evictions, rather than evictions completed by an individual thread.
