I hit a couple failed sessions, including
https://github.com/neutrinoceros/inifix/actions/runs/15723136664/job/44317353045

I'm also able to reproduce this locally with

uv run -p 3.14t --group test pytest

but the result is not deterministic: some sessions still succeed.
This is unlikely to be a bug in inifix(-cli), and most likely a problem with either CPython itself or pytest.
Since 3.14.0b3 just dropped, I'll try it out as soon as it's available through pyenv to see if the problem persist, and if so, will report where due.
