dummy_threading --- Drop-in replacement for the threading module

Source code: Lib/dummy_threading.py

[UNKNOWN NODE transition]

This module provides a duplicate interface to the threading module. It is meant to be imported when the thread module is not provided on a platform.

Suggested usage is:

try:
    import threading as _threading
except ImportError:
    import dummy_threading as _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.
