This doesn't look typical of the problems we've been discussing.
First, they appear to occur more with -CURRENT, and secondly they
don't affect the ping times. What I've been seeing is that everything
is fine until a collision occurs, after which something times out and
it takes a 1 second timeout before it continues. It's easiest to see
with long ftp transfers.

Mine worked fine under 3.x. The problem seems to have crept in in
about October last year (1999).

That may be the answer for Darren's problem. It's definitely not the
case for the ones we have been discussing on -mobile.
