title: What is true sharing?
body: <p>While reading <a href="https://stackoverflow.com/questions/39680206/understanding-stdhardware-destructive-interference-size-and-stdhardware-cons">this</a> question I  encountered the terms “false sharing” and “true sharing”. I read what false sharing is, but I can’t find anything on true sharing. Although in the mentioned question the term is described as “constructive interference” I still don’t understand what it means.</p>
