 // * Callbacks are registered by AddLocationUpdateCallback() and will keep
 //   receiving updates until the returned subscription object is destructed.
 // The application must instantiate the GeolocationProvider on the UI thread and
 // must communicate with it on the same thread.
 // The underlying location arbitrator will only be enabled whilst there is at
 // least one registered observer or pending callback (and only after
 // UserDidOptIntoLocationServices). The arbitrator and the location providers it
 // uses run on a separate Geolocation thread.
