Rollup merge of #144185 - purplesyringa:poisoning-wording, r=Amanieu

2025-08-02T09:24:22+00:00

Document guarantees of poisoning This mostly documents the current behavior of `Mutex` and `RwLock` (rust-lang/rust#143471) as imperfect. It's unlikely that the situation improves significantly in the future, and even if it does, the rules will probably be more complicated than "poisoning is completely reliable", so this is a conservative guarantee. We also explicitly specify that `OnceLock` never poisons, even though it has an API similar to mutexes. Fixes rust-lang/rust#143471 by improving documentation. r? ``@Amanieu``

clean up existing poison files
