As it turns out:

1.164        (tls      22-Apr-04): int  tcp_do_newreno = 1;     /* Use the New 
Reno algorithms */

This was apparently the reason for a 16% drop in my wireless throughput a 
while back, which I had misattributed to switching wireless drivers.

I am rather shocked that it was enabled when it was known to be broken.
