Should this be backported or is it not worth it? |

To 3.13? I don't think it's worth risking breakage. |

This is an alternative to gh-126908, and I'm a lot happier with this. Sam's suggestion of using a list turned out to be pretty nice, with the exception of
unregisterbeing a little wonky. I suspect we could improve that a little by adding a private API for removing from a list more cleanly, but that's work for later. FWIW, both this PR and the other one will have trouble backporting due to the runtime structure changing size.atexitfrom threads in free-threading build segfaults #126907
