But, as I pointed out, if you have already worked out what you need next,
why not just do the asynchronous I/O yourself?  The hard part is figuring
out what to tell Q5ADVISE.  The part that Q5ADVISE does is just the I/O
initialization.

As I said, sophisticated users have been doing this stuff in software
for years.  What do they need hardware VM for?
