Improve fairness of application eviction

            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.
