@michaelandrepearce
> this is great stuff!!! looking forward to it.
The commit here is just mine :P
I've removed the part of Otavio for the resons below..
@clebertsuconic @michaelandrepearce
I need your advice re this one indeed: I think that the changes of Otavio to
enable cross-compilation and improve (a lot!!!) the compilation process deserve
its own PR, wdyt?
This commit is a change in the mechanics of how we use libAIO and I'm not
sure is ok to tied them together: the changes of Otavio are useful per se...

> On LibAIO is possible to retrieve the I/O completion events without
> using io_getevents sys-calls by reading the user-space ring buffer used by the
> kernel to store them.
> This is already beneficial for very fast disks and necessary for further
> improvements
> of ASYNCIO Journal to leverage (very) fast low-latency disks by going
> completly
> lock-free.
