---------------------------------
Ok, you've convinced me. I am +1 on this patch. If you want to commit this as
is, I will fix the perror() in the AIO_MODE_NATIVE code.

> linux native AIO has the ability to signal the event thread to get off the
> poll and service the disk via the io_set_eventfd() call. linux native AIO
> scales better than the thread-based IO, but the current implementation can
> introduce delays on lightly loaded systems because of the thread is waiting
> on epoll(). This can be remedied by using io_set_eventfd
