Shit, i'm sorry man i totally droped the ball on this.
i haven't looked at your latest patch, but catching up on the comments you general API compatibility approach sounds fine to me -- you may want to follow up with Adrien or Yonik to sanity check your decay code, because i didn't fully understand what you guys were talking about the first time it came up.

> SOLR-2906 gave us an inefficient LFU cache modeled on FastLRUCache/ConcurrentLRUCache. It could use some serious improvement. The following project includes an Apache 2.0 licensed O(1) implementation. The second link is the paper (PDF warning) it was based on:
> https://github.com/chirino/hawtdb
> http://dhruvbird.com/lfu.pdf
> Using this project and paper, I will attempt to make a new O(1) cache called FastLFUCache that is modeled on LRUCache.java. This will (for now) leave the existing LFUCache/ConcurrentLFUCache implementation in place.
