      WT doesn't trigger eviction until the LAS score reaches a high value. I think 95 is safer for the snapshot window cache pressure threshold, so that we do not stop servicing 'snapshot' read concern operations while the cache pressure remains unchanged because WT doesn't think it high enough for concern yet.
