Not all DB adapters are fully non-blocking.  If you want to do uncached
filesystem I/O, you'll either have to use threads or block, too.

Maybe not CPU usage, but probably more memory.  But this is probably the
most compatible with existing apps/gems and Ruby stdlib (assuming you
use Linux).

Fwiw, I usually go with this one (or something close[1]) when uncached
disk I/O is a requirement.

If you're not on Linux, (nginx + (portable)ThreadPool) should get you
close to XEpollThreadPool.

Likewise for (nginx + (portable)ThreadSpawn) and XEpollThreadSpawn
