If it makes you happy, write a function like:

def construct_and_run(*args, **kargs):
    thread = construct_it(*args, **kargs)
    thread.start()
    return thread

my_thread = construct_and_run(...)

However, be forewarned that the thread might do quite a bit of stuff
before construct_and_run returns and before my_thread gets set.  That
is, it's a race condition.

Happy Hacking!
