Avoid `thread::panicking()` in non-poisoning methods of `Mutex` and `RwLock` `Mutex::lock()` and `RwLock::write()` are poison-guarded against panics, in that they set the poison flag if a panic occurs while they're locked. But if we're already in a panic (`thread::panicking()`), they leave the poison flag alone. That check is a bit of a waste for methods that never set the poison flag though, namely `get_mut()`, `into_inner()`, and `RwLock::read()`. These use-cases are now split to avoid that unnecessary call. |
