This "Limited Transmit" option, is that configurable somewhere and does that 
work-around the bug (a quick grep tcp on sysctl -a doesn't yield something 
recognizable)?

Seen this this morning while doing a `cvs -d/home/ncvs update src', logged in 
via ssh in a GENERIC kernel of 2004-01-10. This was via a chello Netherlands 
cable connection - an ISP famous for it's high bandwidth and equally high 
packet loss, so it fits the profile.

I'll try Andre's patch regardless, but if it doesn't work, it would be nice if 
there's an alternative (maybe mention that in UPDATING as well).
