I spent the last few days figuring out how to go about doing something that could be "superpoll" [..] There is not yet any reason to assume Mongrel2 will improve from superpoll. For instance, if ATR > 0.6 only happens in low volume situations, epoll suffices. When ATR < 0.6, you need epoll for better performance. In both regimes, epoll is then either an acceptable or the best solution. There is no experimental evidence to suppose Mongrel2 servers will operate in the ATR > 0.6 regime, without epoll being able to handle the volume anyway. Other implementers of webservers aren't stupid or shortsighted either and it seems likely that superpoll has occurred to a few of them, but that they found it wouldn't improve matters. As long as you don't know the ATR in practice, it seems premature to start on abstractions and doing the experiments in this blogpost?
