+dtu for pinpoint error. Going to try re-bisecting between the revisions with the biggest gap on the chart.

Looks like a crazy noisy metric with a huge regression range.

Pinpoint seems to indicate that it's my CL, so assigning it to me.

Also, it's a regression on a micro benchmark for a general dispatch mechanism that we need for all future Oilpan marking improvements, so WontFix.
