------- Additional Comments from Shawn Singh <shawnsingh at chromium.org>
This patch passes all 7 tests attached on this bug when testing manually (using
usleep() to make main thread really slow).  Changelogs and unit tests still
need updating.	Compared to the previous patch, for now I only modified
CCLayerTreeHostCommon.cpp.
