15.4 dummy_thread -- Drop-in replacement for the thread module

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 as _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.
