Is this needed because the dispatcher goes from NPAPI to NM after you install
the host components? If so, please add a comment explaining.

     onDispatcherInitialized();
   }

As before, if this is going to be long-lived, let's discuss; the dispatcher
should not be exposing the underlying interfaces.

I do plan to remove this in the subsequent CL's when I remove the dispatching
code.
