   The function is synchronous, but it should be implemented so that it completes as 
   soon as possible, allowing the notifier framework to enforce its priority mechanism.

   function unless the notifier is likely to finish implementing its functionality immediately.

  Starts the notifier.

  This is called as a result of a client-side call to the asynchronous function 
  RNotifier::StartNotifierAndGetResponse(). This means that the client is waiting, 
  asynchronously, for the notifier to tell the client that it has finished its work.

  It is important to return from this function as soon as possible, and derived 
  classes may find it useful to take a copy of the reply-slot number and the 
  RMessage object.

  The implementation of a derived class must make sure that Complete() is called 
  on the RMessage object when the notifier is deactivated.

  This function may be called multiple times if more than one client starts 
  the notifier.

  @param   aBuffer    Data that can be passed from the client-side. The format
