Ok, so I can't see anything obviously wrong with this, or anything I
can object to. It's still fairly complicated, and I don't love how
hard it is to follow some of it, but I do believe it's better.
IOW, I don't have any objections. Al was saying he was looking at the
io_uring code, so maybe he'll find something.
Do you have these test-cases as some kind of test-suite so that this
all stays correct?
