Async IO is good 'cause you may start more then one IO request simultaneously, which means that you don't have to wait for them. The IO requests will inform the invoking process by sending a signal
(typically, SIGIO) when it's done. Read man pages for aio_read and
aio_write.
As for the NT/Win 2K, it sends a BSOD to inform that the IO is done. Ceterum censeo Microft esse delendam.....

Hi !

There is an event (I think it is 10351) can be used to trace the AIO system calls and this event is specific to solaris.

Level 1 traces the errors &
Level 2 traces the System calls
