+      # Requires ansible 1.7+

+        yum: name=docker-io state=installed

+        register: yum_sleeper

+        until: job_result.finished

+   If the value of ``async:`` is not high enough, this will cause the 
+   "check on it later" task to fail because the temporary status file that
+   the ``async_status:`` is looking for will not have been written
