True. The glibc aio is by default LinuxThreads based. But it is not the 
end of the world.

There is POSIX style AIO library using the native AIO available here: 
http://www.bullopensource.org/posix/

And extensions of native AIO to not require O_DIRECT available here:
http://www.kernel.org/pub/linux/kernel/people/suparna/aio/

and a suitable linux-aio mailinglist for more info on both projects.
