Description Yuta Kitamura 2012-02-22 18:03:41 PST 
Chromium's webkit_unit_tests started to fail since a change in bug 78549.

[ RUN      ] CCOcclusionTrackerTest.surfaceOcclusionWithOverlappingSiblingSurfaces
ASSERTION FAILED: layer->targetRenderSurface() == m_stack.last().surface
third_party/WebKit/Source/WebCore/platform/graphics/chromium/cc/CCOcclusionTracker.cpp(217) : bool WebCore::CCOcclusionTrackerBase<LayerType, RenderSurfaceType>::occluded(const LayerType*, const WebCore::IntRect&) const [with LayerType = WebCore::LayerChromium, RenderSurfaceType = WebCore::RenderSurfaceChromium]

This affects the following two tests:
  CCOcclusionTrackerTest.surfaceOcclusionWithOverlappingSiblingSurfaces
  CCOcclusionTrackerTest.surfaceOcclusionInScreenSpace

I'm going to disable these two tests for now. Please fix this.

Oops, race condition seems to have occurred. I'll undo the change disabling tests.
