Why?  The retransmitted Handshake packets aren't and in this case these are the ones that will run the CWND down.  The 1-RTT PING barely counts.

Can't we just let the CWND burn down?  Do you really think that by this point you will want to send more than CWND worth of these?  I know that it's small at this point (maybe just one packet more than baseline), but if we use INIT_CWND = not_too_small, then we get quite a few goes before this becomes terminal.
