``dummy_threading`` --- Drop-in replacement for the ``threading`` module
************************************************************************

This module provides a duplicate interface to the ``threading``
module.  It is meant to be imported when the ``_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.
