title: Detecting "Error 106 net::ERR_INTERNET_DISCONNECTED)"
body: <p>Is there anyway to detect in a background extension when Chrome shows the page "Error 106 (net::ERR_INTERNET_DISCONNECTED): The Internet connection has been lost." ?  I have tried registering a listener with both <code>chrome.webRequest.onErrorOccurred.addListener</code> and <code>chrome.webNavigation.onErrorOccurred.addListener</code> but neither listener is called when a "Error 106" occurs.  My listeners are being called correctly for other errors such as "net::ERR_NAME_NOT_RESOLVED".</p>
  
  <p>I'm targeting Chrome 22.0.1229.94 in a Window 7 environment.  The larger goal is to provide custom messaging (in a separate tab) when Internet connectivity is lost.</p>
