In Chapter 15, we gave a value multiple owners by using the smart pointer
`Rc<T>` to create a reference counted value. Let’s do the same here and see
what happens. We’ll wrap the `Mutex<T>` in `Rc<T>` in Listing 16-14 and clone
-the `Rc<T>` before moving ownership to the thread. Now that we’ve seen the
-errors, we’ll also switch back to using the `for` loop, and we’ll keep the
-`move` keyword with the closure.
