Hmm, unless your threads are spawned by daemonized threads; the value
always defaults to false. That's why I said it defaults to False. Hows
this:

"""A boolean value indicating whether this thread is a daemon thread
(True) or not (False). This must be set before start() is called,
otherwise RuntimeError is raised. Its initial value is inherited from
the creating thread; the main thread is not a daemon thread therefore
all threads created in the main thread default to daemon = False.

The entire Python program exits ..."""
