  27             # import FCNTL, which doesn't exist.  That raises an ImportError,

  30             # but shouldn't.  As a result, test_pty crashes with an
  31             # AttributeError instead of an ImportError, and regrtest interprets
  32             # the latter as a test failure (ImportError is treated as "test
