# Think of rate limiting as a bucket leaking water at 1cc/second.  The
        # bucket can hold as many ccs as there are seconds in the rate
        # limiting period (e.g. 3600 for per-hour ratelimits), and if you can
        # perform N actions in that time, each action fills the bucket by
        # 1/Nth of its volume.  You may only perform an action if the bucket
        # would not overflow.
