// care must be taken to balance performance against excessive CPU usage. It is
// recommended to enable the CefSettings.external_message_pump option when using
// this function so that CefBrowserProcessHandler::OnScheduleMessagePumpWork()
// callbacks can facilitate the scheduling process. This function should only be
