Note, this behavior is also observed under 3.1.1 (5525.18). The slow down as a
percentage and in terms of milliseconds is not as extreme, though I don't know
whether that qualifies this as a regression. A comparison of the 1st and 5th
runs under 3.1.1, on the same machine as I used for r34130, is below:
