	Followup on JS timing granularity: turns out that it's not JS timing errors after all! Instead, it's the synthetic load I was using, which was to multiply a pair of numbers. If the load is changed to be addition of numbers, the measured time is a clean linear function of the number of additions. So the mystery becomes one of why multiplication in JS sometimes takes about 16ms longer than expected, but at least we're not suspicious about our measurement tools.
