:mod:`_dummy_thread` --- Drop-in replacement for the :mod:`_thread` module

.. module:: _dummy_thread
   :synopsis: Drop-in replacement for the _thread module.

Source code: :source:`Lib/_dummy_thread.py`

.. deprecated:: 3.7
   Python now always has threading enabled.  Please use :mod:`_thread`
   (or, better, :mod:`threading`) instead.


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

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.
