The history shows a pretty clear regression point at r275890. Will work on reproducing the failures, and verifying the regression point.

It seems super unlikely to me that it's due to r275890. But must be very close to it. Perhaps r275889 or r275887?

I've been trying for several days to reproduce the failures, and have been unsuccessful. I've ran on Debug, Release, and Production builds. I've iterated up to 10000 runs. And I've ran in parallel using child-process=1 and child-process=50. None of which have led to a reproduction of the failure. Due to this, I'm still uncertain of the regress point.
