 // The eviction policy is a very simple pure LRU, so the elements at the end of
 // the list are evicted until kCleanUpMargin free space is available. There is
 // only one list in use (Rankings::NO_USE), and elements are sent to the front
 // of the list whenever they are accessed.
 
 // The new (in-development) eviction policy adds re-use as a factor to evict

 // When we have to evict an element, first we try to use the last element from
 // the NO_USE list, then we move to the LOW_USE and only then we evict an entry
 // from the HIGH_USE. We attempt to keep entries on the cache for at least
 // kTargetTime hours (with frequently accessed items stored for longer periods),
 // but if we cannot do that, we fall-back to keep each list roughly the same
 // size so that we have a chance to see an element again and move it to another
 // list.
