Well, how about doing it at the beginning of its run() method, e.g. in a
Thread subclass:

    class MyThread(threading.Thread):
        def run(self):
            self.thread_ident = thread.get_ident()
            threading.Thread.run(self) # or any other stuff


Also, I don't think get_ident() is often useful when using the Threading
module, since you can just use the id() of the current Thread object
instead.
