The problem here is that it only tracks the window size as

My patch is wrong as the acked count is already integrated
by the time we reach this spot. I'm working on a better
implementation.
Ok, I'll look forward to seeing and testing it.
Please test this patch:

I just completed a number of tests and inspected the debug output as
well as the corresponding tcpdumps. In all could simulate it behaved
correctly now with regard to tracking the window and updates.
