"""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.
