Browse Source 
A multiprocessing bug is fixed in 3.13.8, see [https://docs.python.org/3.13/whatsnew/changelog.html](https://l.workplace.com/l.php?u=https%3A%2F%2Fdocs.python.org%2F3.13%2Fwhatsnew%2Fchangelog.html&h=AT0qUhHJq5c2UJvQaq9_MrSo0mVhwn1VOfq1nDQl2C1UOhDI80RMbzVayhG7LSAT1uYHKtkftKnBDwiGMhbw0YRvQLe5vwE01qejpPFautHvU3LXeOE1KChPykqz3qnCRzk7czu_iNzQ05shR4F1N_qYOzR5YxejA52ZZQ), [gh-126631](https://github.com/python/cpython/issues/126631)

So this test will fail when we update to python 3.13.8
