But there is a (nearly undocumented) native Linux AIO API.

  And that's better?

    It is better in the sense that it is actual AIO. Whether you want AIO so badly that you're willing to suffer the lack of docs is a case-by-case decision.

    Yes. The io_submit based async io API is much better, especially if you are doing lots of iops.
