Bryan reports (in #4965): I notice that -hT doesn't seem to be counting
wall clock time properly as of 7.0.3, and this persists in HEAD too. Look
at the PDFs I attached to this bug: the first (with 6.12.3) counts time
correctly, while the second and third under-count by a large amount. For
example, the actual wall-clock time for HEAD was the same as 6.12.3, about
15 seconds, but the X axis in the chart only runs up to 5 seconds. Weird.
