Agreed. The making lots of connections was a bad idea. However, I've
rarely seen low latency and low bandwidth go together. I've also
problems connecting accross high loss links more often. Sure, it is a
statistical argument.
I still think that the n connections wouldn't be that expensive. The
cost, iirc, of a connection that drops is very low. I can certainly
see enough problems with it to encourage jdp to not implement it,
despite being the person that proposed it...

Agreed. But in the abasense of intellegence at one end is causing
problems at the other end.
FWIW, I've found that *MUCH* better response times since I started
using cvsup{6,7,8} on a regular basis than I was getting from
cvsup{1,2,3}. I'm also seeing much faster response times from 6,7,8
than cvsup-master (yes, I know I'm not supposed to use that, but there
are rare times I need to snag the latest change right away...).
I've not tried cvsup 4,5 in a while, but did have trouble connecting
to 5 while polishing my script.
