The current AIO module is network AIO only and works under FreeBSD only.
It's not maintained and now may not work at all. FreeBSD's AIO network
support is unenfficient (no zero copy and not scaleable) and buggy (when
I developed module I saw kernel panics several times).

There is still no disk AIO support.
