:mod:`dummy_threading` --- Drop-in replacement for the :mod:`threading` module
==============================================================================

.. module:: dummy_threading
   :synopsis: Drop-in replacement for the threading module.


This module provides a duplicate interface to the :mod:`threading` module.  It
is meant to be imported when the :mod:`_thread` module is not provided on a
platform.

Suggested usage is::

   try:
       import threading
   except ImportError:
       import dummy_threading

Be careful to not use this module where deadlock might occur from a thread being
created that blocks waiting for another thread to be created.  This often occurs
with blocking I/O.
