There's a race in cc somewhere from commit to draw. I don't know exactly
how to repro the race yet even though I have a high probably fix. This
CL is intended to catch the race in the wild and produce a stack trace
in a crash log. Hopefully from there we can acertain repro steps.

Once repo steps are produced locally (either via user interaction or
unit test) then this CL will be reverted.
