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