In my unload handler for the outer DOM window I get called with window 
location = about:blank. But when I clean up the window, it has a new 
location and deleting it deletes the information I want:

   // domWindow.location is about blank here...
   setTimeout(function delayCleanup() // to allow the unload handlers to 
complete
   {
       // domWindow.location is chrome://test/content/testDialog.xul
       TabWatcher.unwatchTopWindow(domWindow);
   });

So somehow about:blank is getting an unload message but the domWindow 
object I obtained from the unload handler event.target.defaultView; is 
morphing into the window that supports my dialog.
