  4. '''Faux ``threading`` version using ``dummy_thread`` instead of ``thread``.
  5.  
  6. The module ``_dummy_threading`` is added to ``sys.modules`` in order
  7. to not have ``threading`` considered imported.  Had ``threading`` been
  8. directly imported it would have made all subsequent imports succeed
  9. regardless of whether ``thread`` was available which is not desired.
