dummy_threading — Drop-in replacement for the threading module

Source code: Lib/dummy_threading.py

Deprecated since version 3.7: Python now always has threading enabled. Please use threading instead.

---

This module provides a duplicate interface to the threading module. It was meant to be imported when the _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.
