This may have Patches 3 and 4 look good to me except that for me, a cache is something that lets us avoid an expensive computation. But as far as I know, we're not planning to perform the expensive computation in the absence of a cache. Maybe the word "record" would fit better. This is nit-picky, though, and if others think that the word "cache" fits here, that's fine by me too.
