I could reproduce it by running services.exe tests in a loop. I found
that it's fixed by patches I have in my branch that are meant to improve
immediate returns from read/write. On closer look, they not only improve
perf, but also fix how we handle errors on ntdll side. Sorry I didn't
catch it earlier, I would plan patch series differently. They are only
drafts I meant to send as follow ups, so I need to finish them, test a
bit more and put earlier in the patch series. I will work on that, but
how does it fit release plans?

Thanks,
Jacek
