``_dummy_thread`` --- Drop-in replacement for the ``_thread`` module
********************************************************************

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

Suggested usage is:

   try:
       import _thread
   except ImportError:
       import dummy_thread as _thread

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.
