See https://github.com/python/cpython/actions/runs/13604468612/job/38034332952?pr=121185. Not sure if it's a flaky or a real bug. But I'll start reporting issues on free-threading builds from now on, just in case.

Thanks for reporting theses issues. This one is a duplicate of:

• test_concurrent_futures.test_wait.ThreadPoolWaitTests.test_timeout flakes frequently on free-threaded Windows x64 #128364

Ah thank you. Do you prefer me to first @ you on Discord so that you can check whether it's a duplicate or not? it's a bit hard to find the issues as I don't necessarily know which one is the relevant one (ok, in this case I searched test.test_concurrent_futures.test_wait but because there was some markdown, I guess GH didn't find it =/)

Please just file the issue if you don't see an existing one. It's not a big deal if there's an occasional duplicate issue.
