:mod:`_dummy_thread` --- Drop-in replacement for the :mod:`_thread` module
Source code: :source:`Lib/_dummy_thread.py`
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.
