    Sure, send us your patches. We've got a couple questions on this subject
    and I think the problem stems from the plethora of tracing options ns
    gives people. I've always taken queue traces and distilled them down to
    the packet arrivals I've cared about and ran those through tcptrace
    without any problems, but I suppose other people do things differently :).
    So, thanks a lot for looking into this, and I'll be happy to integrate
    your patches if you'll mail them to us. Could you give us a couple of
    lines of the TCL code you use to set the trace up too, so we could use
    it as an example for people?
