The discussion has been most complete, I guess at this point is you can't fix the sender to stop this anti-social behaviour, you might try using iptables to "mangle" the PSH off from this host or rate limit the ACKs, or some other hack. None of which is a "solution," just some interesting things to try.
As noted, the core problem is that TCP doesn't like really asymmetric bandwidth.
