relevant line: unsafe impl<T: ?Sized + Send> Sync for Mutex<T> { }
It really does seem like using `PhantomData` would have made more sense than opting out of the autotrait impl

PhantomData<&mut T> I suppose? Perhaps. I wonder how the variance of that works out. Actually, there's a chance variance is wrong there.

Yes. The variance shouldn't change since it'll still have the `&Mutex<T>` reference with the same lifetime.
