At this point, I think we've come full circle.  Can we all agree that
this concept is a *potential* source of improvement in a variety of
situations?  If we can agree on that, perhaps we should move to the next
stage in the process, validation?

How long do you think it would take to develop something worthy of
testing?  Do we have known test cases which will properly (in)validate
the approach that everyone will agree to?  If code is reasonably clean
so as to pass the smell test and shows a notable performance boost, will
it be seriously considered for inclusion?  If so, I assume it would
become a configure option (--with-aio)?


Regards,
Greg
