--- Comment #3 from ide at jameside.com ---
It would also be desirable for JS evaluation to be responsive if the app has been idle for a while. For example, if UITouch events invoke -[WKWebView evaluateJavaScript:completionHandler:] and wait for a result via the completionHandler before updating the screen, using a cached JSContext could save a frame or two, assuming 60 FPS. So, it'd be useful to keep the JSContext around for a longer period of time until an event like memory pressure or backgrounding the app occurs.
