Comment on attachment 299616 [details] Patch r=me Should we also measure how often a contextLoss handler would have been called if it were present/is called if it is present?

I don't think this is important at the moment. What we want to know is would it be safe for us to take away / restore the WebGL context and rely on the pages dealing with context loss via those event handlers.
