 1:mod:`dummy_thread` --- Drop-in replacement for the :mod:`thread` module
 2========================================================================

 4.. module:: dummy_thread
 5   :synopsis: Drop-in replacement for the thread module.
 6
 7.. note::
 8   The :mod:`dummy_thread` module has been renamed to :mod:`_dummy_thread` in
 9   Python 3.0.  The :term:`2to3` tool will automatically adapt imports when
10   converting your sources to 3.0; however, you should consider using the
11   high-lever :mod:`dummy_threading` module instead.

14This module provides a duplicate interface to the :mod:`thread` module.  It is
15meant to be imported when the :mod:`thread` module is not provided on a
16platform.
17
18Suggested usage is::
19
20   try:
21       import thread as _thread
22   except ImportError:
23       import dummy_thread as _thread
24
25Be careful to not use this module where deadlock might occur from a thread
26being created that blocks waiting for another thread to be created.  This  often
27occurs with blocking I/O.
