I've already fixed this for main and 3.14 in gh-127990, but that wasn't backported to 3.13. I'm not planning on fixing any other 3.13 docs, but
PyThreadState_Swapis especially bad, because the documentation says you need to hold the GIL to call it, which is wrong and would defeat the whole point of the function if it were true. I've seen people get confused by that on several different occasions.📚 Documentation preview 📚: https://cpython-previews--133900.org.readthedocs.build/en/133900/c-api/init.html#c.PyThreadState_Swap
