You should pick up the kevent work :)
3 months ago i verified the published kevent vs. epoll benchmark and
found that benchmark to be fatally flawed. When i redid it properly
kevent showed no significant advantage over epoll. Note that i did those
measurements _before_ the recent round of epoll speedups. So unless
someone does believable benchmarks i consider kevent an over-hyped,
mis-benchmarked complication to do something that epoll is perfectly
capable of doing.
You snipped the key part of my response, so I'll say it again:
Event rings (a) most closely match what is going on in the hardware and
(b) often closely match what is going on in multi-socket, event-driven
software application.
To echo Uli and paraphrase an ad, "it's the interface, silly."
This is not something epoll is capable of doing, at the present time.
