been using it heavily for various internal projects and test suites with
It's great for test suites because it starts up faster and (fails more
loudly/quickly) than Rainbows! That said, I'll be publically releasing
a full Rack application soonish that uses Zbatery in its test suite.
Rainbows! is (probably) better for heavy production use, especially on
medium SMP (2-16 cores) boxes where multiple worker processes can
amortize GC costs.
Since Zbatery is 99%-reliant on Rainbows! code, I think I'll keep all
discussion of it on this mailing list if it's alright with everyone.

deployments on larger SMP (or even NUMA) systems, let us know!
I doubt huge SMP/NUMA boxes are practical for HTTP applications
at this point due to bus limitations, but wouldn't mind being
