So it's a Windows and MacOS bug then? Ie, no shadow should fall on io_uring really?

That said, nice dig figuring this out. These type of bugs can be really frustrating to round up.

It is a Windows and MacOS bug, but only visible with the io_uring change in behavior.

Problem is we have to fix the server, as even when buggy, one billion clients can never be wrong.
