+: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 as _threading
+   except ImportError:
+       import dummy_threading as _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.
