Sort of. It does not remove all that could be removed, it removes all
objects that is either expired or above the dynamically calculated max
LRU age.

It only looks at one hash bucket, and is optimized to run quickly with a
reasonalbe good result. If the cache is large enought it performs very
well, if the LRU age is short (the cache cache is to small) then it does
a not so good job..
