LFU cache and autowarming
If I was to use the LFU cache instead of FastLRU on the filter cache, if
I enable auto-warming on that cache type - does it warm the most
frequently used fq on the filter cache? Thanks for any info!

Well, I haven't tested it - if it's not ready yet I will probably avoid
for now.

I wrote that cache. It's a really really crappy implementation, I would
only expect it to work well if it's the cache is very very small.
I do have a replacement implementation that's just about ready, but I've
not been able to find 'round tuits to work on getting it polished and
committed.
