Freebsd have had kqueue for the longest time. Unfortunately Linux didn't adopt it for political reasons and osx did a half port and dropped disk io support.

  kqueue doesn't work for disk. It always reports ready to read.

    If you try to use the readiness-based kqueue events that is the case, but the completion-based aio events do work with disk files on kqueue.

      Ah, that slipped my mind.

    On FreeBSD kqueue does work for normal files if you use aio_* and SIGEV_KEVENT.
