I think you read too much into that list. :) 

I was the author of that page but only in the sense that I took one massively
large "Open Projects" page and dispersed it into individual project files. 
The project is to implement aio_ defined in aio.h as specified by the
Open Group.  aio_fsync shouldn't be terribly hard to add.  I don't
know about aio_suspend().
