Document guarantees of poisoning
This mostly documents the current behavior of `Mutex` and `RwLock` 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.
