I figured out what is going on here.  The sipp csv file records the
result code for each call, and records the time the call was _initiated_.
The report sorts the call data by start time before generating the graph.
Therefore calls that run long and then fail get reported as an IHS earlier
in the graph than they do in the manager log (where they show up when
the call _ends_).  Part of the confusion (but only part) is because I
was using very short steps while testing the benchmark system.
