    Summary: CopyCell lacks bounds on its Send trait allowing for data races

    Details: `CopyCell<T>` is a `Cell`-like type that is implemented for any type `T` that is `Copy`able. It's `Send` trait has no bounds on the contained type. As not all `Copy`able types are thread safe, for example non-mutable references implement the `Copy` trait, it is possible to send references to types with interior mutability such as `Cell` across threads and cause data races.
