I am building and testing Python 3.6 on the JASMIN Analysis Platform <http://www.jasmin.ac.uk/services/jasmin-analysis-platform/>, which runs Red Hat Enterprise Linux Server release 6.8 on a machine with 48 × Intel(R) Xeon(R) CPU E7-4860 v2 @ 2.60GHz, 2 TiB RAM, and a PanFSⓇ <http://www.panasas.com/products/panfs> distributed file system.  test.test_spwd.TestSpwdNonRoot is failing with FileNotFoundError.  Below is the full verbose output of `./python -m test -v test_spwd`:
