   I've added some unit tests around the cache, and I'm refreshing the performance results with the new cache, with the (new) default maximum size of 1024 entries. Note that Guava's caches never get to that limit, but use some heuristics to remove LRU entries before the cache gets full - this is for cases when the cache is being populated in multiple threads, when the cache would otherwise spend a lot of time in each thread purging the oldest entries.
