Getting memory usage for a CefBrowser?

[DanKegel]

Is there a good way to figure out how much memory a CefBrowser is using?
(I guess there's --remote-debugging-port but I'm looking for something simpler, usable routinely rather than when debugging.)

window.performance.memory looks promising... but is only for the javascript heap, so it doesn't capture native memory use.

https://developer.chrome.com/extensions/processes would be nifty... but that's chrome's interface to its task manager, and isn't part of cef3.
