Ok.  That takes almost a minute on my system.  What's the best way to
notify the engine so the user

        except yum.Errors.RepoError,e:
            self.ErrorCode(ERROR_NO_CACHE,"Yum cache is invalid. Rebuilding.") 
            self.Finished(EXIT_FAILED)
            self.StatusChanged(STATUS_WAIT)
            self._refresh_yum_cache()
            return
?
