Hi,

I still think 2/3 is a legitimate fix. To clarify, I was not trying to
claim that 84 is some magic number in the abstract, and I agree the
packetdrill is artificial.

My point was only that, in the constructed case, the old code can
preserve a scaled window that is larger than the currently backed
receive space, while 2/3 keeps the stored window representable in
scaled units.
That said, I am probably missing the reason why that is not a problem
according to the feedback you all have given.

So I am going to drop it here.

To be clear this has nothing to do with social engineering, just was
trying to fix something that doesn't need fixed I suppose.

Thanks,
Wesley Atwell
