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
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.
