The new patch addresses the problem with LayerChromium reference holding.

It is done by more template indirection. I agree it is a bit nasty. The biggest problem with different LayerList type in main and CC thread is the difference in accessing the raw pointer. I have to write something like:

inline static LayerChromium* getRawPtr(const RefPtr<LayerChromium>& ptr) { return ptr.get(); }
inline static CCLayerImpl* getRawPtr(CCLayerImpl* ptr) { return ptr; }

I wish WTF::Vector has something similar to WTF::HashMap::peek...
