Yes, Yusuke was referring to me.  These messages came from internal tests.  Before your patch, running the script did not produce this output.  After your patch, it does.  I suspect that the tests were always printing these output.  However, your change somehow expose them.  Do you have any idea where your patch enables more verbose stderr/stdout output to be shown?
