Unfortunatly I've got 3.2 on the other end and I can't change it a the
moment.

My guess is that it would solve about 70% of the problems I'm seeing.
but SACK will nearly always do better than new-Reno.. it just needs
more support as well.
What I think would be really cool would be a Vegas/new-reno/SACK
implementation!

BTW looks like we have 2 FreeBSD-2.1 SACK implementations, and a netBSD
VEGAS implementation. We already have new-reno of course.
