title: What's the difference between "memory" and "memory footprint" fields on Chrome's task manager?
body: <p>I'm using Chrome 64 and noticed that there's two fields called "memory" on Chrome's task manager. See the picture below:</p>

  <p>I can't find any explanation of the difference between these fields on Chrome, there's no tooltips available (at least not on macOS). The "memory footprint" field seems to be new, because I don't recall seeing it before yesterday.</p>
