Actually, after reading up on the current state of things, I'm not sure you
can even get POSIX aio on top of kernel aio in Linux. There are also a
few limitations in the 2.6 aio implementation that might prove troublesome:
for example it only works with O_DIRECT.

libaio gives userland access to the kernel aio api (which is different 
from POSIX aio).
