Thanks, Nikolai. epoll looks like the silver bullet (for linux) and
very promising. I can dump a bunch of sockets into it and get the
kernel to let me know which ones get notifications for
reset/read/write.

Do note that you're back to polling, which I understood you wanted to
avoid in the first place ?
Formally yes maybe, but Andrew probably meant just avoiding some
horrible CPU-burning busy-loop.
Despite of the similar name (epoll), substantial shortcomings of
classical polling scheme are gone. Say, you need not use a timeout to be
able to handle any non-socket events like you were forced with select(),
you can wait on descriptors of different types if you wish to, and you
don't have to pass huge arrays all the way.
