--- Comment #7 from Geoffrey Garen <ggaren at apple.com> ---
...I think it's also OK to increase the timer to something like 10s or 30s -- but it's not clear that would fully solve the performance complaint here.

I don't agree with the suggestion to rely on a memory pressure event. Caches that only evict upon memory pressure create a tragedy of the commons where memory pressure events become more common, and then you just always evict all of your caches all of the time. It is preferable, when possible, to evict eagerly when you know you don't need your cache anymore.
