-/**
- * @fileoverview This event handler will dispatch events when
- * {@code navigator.onLine} changes.  HTML5 defines two events, online and
- * offline that is fired on the window.  As of today 3 browsers support these
- * events: Firefox 3 (Gecko 1.9), Opera 9.5, and IE8.  If we have any of these
- * we listen to the 'online' and 'offline' events on the current window
- * object.  Otherwise we poll the navigator.onLine property to detect changes.
- *
- * Note that this class only reflects what the browser tells us and this usually
- * only reflects changes to the File -> Work Offline menu item.
- *

-// TODO(arv): We should probably implement some kind of polling service and/or
-// a poll for changes event handler that can be used to fire events when a state
