The CQ apparently didn't pick up this revert and apply it.

Instead, I reverted with drover.  Silly me to trust the newfangled revert
patchset button.

FYI the revert is wrong. All linked dashboards have recovered before the revert
but we missed it.

We were wrongly led to believe that it was the Blink roll due to a to a commit /
revert that wasn't reported to gardener / sheriff that caused a transient
failure on most bots (thinking about
http://src.chromium.org/viewvc/chrome?revision=285713&view=revision).
