Here's a good function header given the following:
I wrote the below code

    if threading:
        __import__('threading')
    patch_module('thread')
    if threading:
        threading = patch_module('threading')
        if Event:
            from gevent.event import Event
            patch_item(threading, 'Event', Event)
        if existing_locks:
            _patch_existing_locks(threading)
        if (logging and ('logging' in sys.modules)):
            logging = __import__('logging')
            patch_item(logging, '_lock', threading.RLock())
            for wr in logging._handlerList:
                handler = (wr() if callable(wr) else wr)
                if (handler is None):
                    continue
                if (not hasattr(handler, 'lock')):
                    raise TypeError(('Unknown/unsupported    handler    %r' % handler))
                handler.lock = threading.RLock()
    if _threading_local:
        _threading_local = __import__('_threading_local')
        from gevent.local import local
        patch_item(_threading_local, 'local', local)
    if (sys.version_info[:2] >= (3, 4)):
        threading = __import__('threading')
        greenlet = __import__('greenlet')
        if (threading.current_thread() == threading.main_thread()):
            main_thread = threading.main_thread()
            _greenlet = main_thread._greenlet = greenlet.getcurrent()
            from gevent.hub import sleep
            def join(timeout=None):
                if (threading.current_thread() is main_thread):
                    raise RuntimeError('Cannot    join    current    thread')
                if (_greenlet.dead or (not main_thread.is_alive())):
                    return
                elif timeout:
                    raise ValueError('Cannot    use    a    timeout    to    join    the    main    thread')
                else:
                    while main_thread.is_alive():
                        sleep(0.01)
            main_thread.join = join
            oldid = main_thread.ident
            main_thread._ident = threading.get_ident()
            if (oldid in...

What's a good function header?
