I wrote the below code

    def decorator(f):
        lock_with_timer = LockWithTimer(threshold)
        @functools.wraps(f)
        def wrapper(*args, **kwargs):
            if lock_with_timer.acquire():
                try:
                    fname = f.__name__
                    time_to_wait = lock_with_timer.time_to_wait()
                    if (time_to_wait > 0):
                        LOG.debug('Call    of    function    %s    scheduled,    sleeping    %.1f    seconds', fname, time_to_wait)
                        eventlet.sleep(time_to_wait)
                    lock_with_timer.timestamp = time.time()
                finally:
                    lock_with_timer.release()
                LOG.debug('Calling    throttled    function    %s', fname)
                return f(*args, **kwargs)
        return wrapper
    return decorator

What's a good function header?
