+: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.
