+\modulesynopsis{Drop-in replacement for the \refmodule{threading} module.}
+
+This module provides a duplicate interface to the
+\refmodule{threading} module.  It is meant to be imported when the
+\refmodule{thread} module is not provided on a platform.
+
+Suggested usage is:
+
+\begin{verbatim}
+try:
+    import threading as _threading
+except ImportError:
+    import dummy_threading as _threading
+\end{verbatim}
+
+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.
