-// This class listens for notifications from the talk service, and signals when
-// they arrive.  It checks all incoming stanza's to see if they look like
-// notifications, and filters out those which are not valid.
-//
-// The task is deleted automatically by the buzz::XmppClient. This occurs in the
-// destructor of TaskRunner, which is a superclass of buzz::XmppClient.
