Code snippet. Not sure what result actually was. But something failed in the background task. Need to figure out what...

      # Tell the build bot this step failed for the waterfall.                  
      result, description, retrying = self._TopHandleStageException()
      if result not in (results_lib.Results.FORGIVEN,
                        results_lib.Results.SUCCESS):
        raise failures_lib.StepFailure()
