I don't want to get too much into the shortcomings of the existing scheme, except for those things we know to be firmly true.  The only thing that I think can be said definitively is that attempting to send responses one at a time is better than trying to evenly share available capacity between multiple responses.

I expect that the new thing we ship will be much better than that, but it's probably best to let that specification speak for itself.
