I've been having exceptional results while testing this. Very low stales compared to pushpoold, like ~0.1% or less average. Very stable compared to pushpoold. Fast restarts and it picks up the shares it had in the air when you do have to restart. And it runs fast and doesn't eat endless memory, the GC process seems work great. Really fantastic so far.

Wanted to clarify - The only reason I've restarted poolj so far was because I wanted to, not had to.
