It's not -- if you used -i, it died saying weight is zero.

I didn't include this part.

Pushed.


In doing this, I noticed that the latency output is wrong if you use -T
instead of -t; it always says the latency is zero because "duration" is
zero.  I suppose it should be like in the attached instead.  At the same
time, it says "latency average: XYZ" instead of "latency average = XYZ"
as in printSimpleStats, which doesn't look terribly important.  But the
line appears in the SGML docs.
