Jens, your test case showing that this happens on aio too was
appreciated: I was out of town for the holiday weekend, and I'm just now
back home catching up and fixing your test case is the first thing I'm
working on.

But like I said, this wasn't causing test failures when we were using
AIO, it's only since we switched to io_uring that this has become an
issue, and I'm not the only one telling you this is an issue, so ball
very much in your court.
