:mod:`dummy_threading` --- Drop-in replacement for the :mod:`threading` module
==============================================================================
.. module:: dummy_threading
:synopsis: Drop-in replacement for the threading module.
This module provides a duplicate interface to the :mod:`threading` module. It
is meant to be imported when the :mod:`_thread` module is not provided on a
platform.
Suggested usage is::
try:
import threading
except ImportError:
import dummy_threading
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.
