Mutex and Arc both require alloc memory on heap, but Arc<Mutex<T>> seemed to have no need to alloc the memory twice. I mean, the heap allocation of Mutex may be redundant, at least in the case T has a fixed size. Will Arc<Mutex<T>> be optimized? Or am I fundamentally wrong, the two allocations are …

Will something like `Arc<Mutex<T>>` be optimized?
