:mod:`dummy_thread` --- Drop-in replacement for the :mod:`thread` module

========================================================================

.. module:: dummy_thread

   :synopsis: Drop-in replacement for the thread module.

.. note::

   The :mod:`dummy_thread` module has been renamed to :mod:`_dummy_thread` in

   Python 3.0.  The :term:`2to3` tool will automatically adapt imports when

   converting your sources to 3.0; however, you should consider using the

   high-lever :mod:`dummy_threading` module instead.

This module provides a duplicate interface to the :mod:`thread` module.  It is

meant to be imported when the :mod:`thread` module is not provided on a

platform.

Suggested usage is::

   try:

       import thread as _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.
