 """These kinds of tests are less than ideal, but at least they run.
 
 This was an old test that was being run interactively in the top-level tests/
 directory, which we are removing.  For now putting this here ensures at least
 we do run the test, though ultimately this functionality should all be tested
 with better-isolated tests that don't rely on the global instance in iptest.
