Why do you like to put band-aids to things?
Find the real cause of why you may be having problems then cure it;
putting arbitrary hacks just because you can is rather against
the basic principles of engineering.

I'm looking for the real cause.  The current code does not work
as I want it to.  So, I'm changing things.  I would love to try
out any patch you might feel like contributing.

From what I can tell, the old code punishes interfaces who are
running slower at any given time.  My change, I believe, will
allow slower interfaces to gather a bit more quota so that when
they are hit with a burst of traffic, they can spend a little
extra time to clear their buffers.

I would also welcome any argument as to why my code is worse
than the existing code.  And theoretical papers be damned,
I see better results with the change below.  Why is that?
