threading - how to get parent id/name?

Make a Thread subclass that sets a parent attribute on init:

from threading import current_thread

class MyThread(threading.Thread):
    def __init__(self, *args, **kwargs):
        self.parent = current_thread()
        Thread.__init__(self, *args, **kwargs)

Then, while doing work inside a thread started with this class, we can access current_thread().parent to get the spawning Thread object.
