Hmm, but if you look at the patch, in those cases we call OnStateChange,
we actually pass on it's return value:

    hres = IActiveScriptSite_OnStateChange(site, (state = ss));
    return hres;

And that is "S_OK if successful" according to MSDN.  Perhaps you could
follow up with a patch to refine what we have now?
