Nope. I don't believe there is a rule for kicking entries out of the
cache, largely due to the way memory management works with memory
pools.

Well, before the cache existed performance was quite a bit worse than
it is today. It's probably a combination of the work parsing the data
and the disk access (some of which may be cached by the OS).
