Commit Message

Add variation that segments eden and main spaces

The ideas behind these two policies is that we can use a better
strategy than LRU for the W-TinyLfu spaces. The best O(1) policy that
does not use non-resident entries is Segmented Lru, which protects
entries that have multiple accesses within a short time window.

If we can present to TinyLfu the best candidates to chose between,
we can make its admission more effective. It also lets us protect
ourselves from TinyLfu making a poor decision, which the window
mostly resolves.

The results is that segmenting the main space seems to have a 0-2%
improvement to the hit rate. Further segmenting the eden space
seems to be a slight penalty rather than improvement.
