Details

It appears that at least our current path to telemetry is rounding eg GC_SLICE_MS timings to whole numbers of milliseconds, which make the statistics (eg percentiles) jumpy and multimodal, and throw away information about the true distribution. If we're going to be truncated to integers, we ought to be reporting microseconds.
