There are quite a few oddities in the New Reno implementation, and the
point you raise is somewhat valid.  (It would be even moreso if you could
provide tcpdumps to show the effect! <g>)

Jeffrey Hsu <hsu@FreeBSD.org> has been working on improving our NewReno
implementation.  You should drop him an e-mail to see if what he has
developed so far will be helpful to your case.
