Please ignore my previous mail, which *almost* said what I wanted to say.

The AD Draft 3 of the XSH book, in aio_fsync(), does say this.

But this is not a "general" statement for all APIs, just a
statement for aio_fsync(), that only the filedes and the signal
are relevant.

This statement does not apply to aio_cancel(), aio_error() etc.

However, this statement has not been retracted or questioned in
1003.1-1996 or anywhere else -- the intent is that an aio_fsync()
happens right when you ask for it, I guess.

[I didn't write the AIO specs, I've just had years of experience
interpreting POSIX wording....]
