Start working on a FIFOCache.
This is designed to have less runtime cost than the LRUCache.
Mostly because we don't have to do any recording work on *access*
only on update or delete.
As such, we subclass dict directly, because experiments show that
it performed the best. Unfortunately, even though we don't have
a custom __getitem__ implementation, it is still approx 2x slower
than using a raw dict.
