Clever. ;)
I think you're correct since there is a lower bound on cwnd (i.e.,
it can never be less than 1 MSS).
But, I don't think this will actually work all that well -- and it
may be worse for the network than simply setting your TCP to never
adjust cwnd. The problem is that you are spitting out 64KB onto the
network at once. With a burst like that some packet is going to be
lost -- which means you'll end up retransmitting the TCP segment
again (in a 64KB burst). Packets from that segment will likely be
dropped, etc. So, you likely won't be getting much of anything
done.
