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

  17         # but shouldn't.  As a result, test_pty crashes with an
  18         # AttributeError instead of an ImportError, and regrtest interprets
  19         # the latter as a test failure (ImportError is treated as "test
  20         # skipped" -- which is what test_pty should say on Windows).
