> We will need 32 bit support. I remember there being someone in the
community on a user thread being on 32 for valid reason.
Yep. that's why I've summoned @orpiske :) I will probablu need some help
with CMake (that I'm not that use to it) in order to provide 2 different
implementations for the barriers (x86 and x86_64): I'm used to write/read
assembly but really bad to use build tools :P

> 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.
