No, 2.0 does not have this problem. The entire tcp retransmission
code has been rewritten a few times lately. I rewrote it sometime
in the run up to 2.0.0 to get retransmissions right, and Pedro
Roque rewrote it again for 2.1 in the process of rationalizing
and rewriting most of the TCP stack.

Anyway, in general TCP bugs in performance tend to be very subtle
things. Changes of 1 line usually make all the difference.
