erikchen@chromium.org changed reviewers:
+ tsepez@chromium.org

[erikchen, 2016-04-05 00:47:08]

tsepez: Please review.

Once this lands and sticks, I'll follow up with a large refactor [the method
should be renamed, one of the variables isn't used, the implementation should
just forward to base::SharedMemory, etc.]
