LibraryCommands.GetCounts hits the file cache hard. The previous cache implementation was linear list, so finding an entry by ID was (n). When you consider that each book may have many files, the number of cache entries could grow to many multiples of the library size. The new cache uses a dictionary with the ID as its key, and a CacheEntry list as its value.
