title: When do I really need to use atomic<bool> instead of bool?
body: <p>Isn't <code>atomic&lt;bool&gt;</code> redundant because <code>bool</code> is atomic by nature? I don't think it's possible to have a partially modified bool value. When do I really need to use <code>atomic&lt;bool&gt;</code> instead of <code>bool</code>?</p>
