Socket polling method

[outrider-jkoch]

Has it ever been considered to use a different polling method besides select() such as poll() or epoll()? I see the implementation changed slightly at version 0.11.0 to start abstracting some stuff out of poll_client() and moving it into some implementation methods. Perhaps there aren't any substantial performance gains to be had by changing but from my understanding the Linux community has been slowly moving away from using select() in favor of one of the others due to slightly better performance and the ability to handle potentially larger file descriptor values.
