WARNING: This module is architecture-dependent and will not likely work
         on lesser-used architectures (see Changes). If the module (esp.
         aio_read and aio_write) doesn't work, please report this and I'll
         fix it for you. I promise ;)

WARNING: This module requires 64 bit file offset functionality only found
         in linux-2.4 and later. You can still compile this module on
         older linuxes, but it won't run.

DEVELOPERS: It is not difficult to get rid of this limitation, ask me and
            I'll tell you what you need to change (and test, so I can add it!).
