Well, there are those humorous edge cases where you compress a tiny
amount of uncompressible data, and the "compressed" version ends up
being larger. Not sure if that applies to the specific algorithms that
btrfs uses, but I've seen it happen with tiny datasets before. Even
worst case could be hard to get right perhaps!
