Message 162870 - Python tracker

The XincludeTest test-case in test_xml_etree is now skipped, because it fails in an intermittent manner. I can reproduce the failure when running full regrtest with -j1, but not -j8, and not when run individually.

The failure is most likely due to the test itself, in the way it imports the Python ET, leaving _elementtree out.
