remove the `T: Sync` requirement for `RwLock<T>: Send`
That requirement makes sense for containers like `Arc` that don't uniquely own their contents, but `RwLock` is not one of those. This restriction was added in https://github.com/rust-lang/rust/commit/380d23b5d4b9fb8f5f0ebf178590f61528b2483e, but it's not clear why.
