16.5. "dummy_thread" --- Drop-in replacement for the "thread" module
********************************************************************

Catatan: The "dummy_thread" module has been renamed to
  "_dummy_thread" in Python 3.  The *2to3* tool will automatically
  adapt imports when converting your sources to Python 3; however, you
  should consider using the high-lever "dummy_threading" module
  instead.

**Source code:** Lib/dummy_thread.py

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

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 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.
