This patch will likely (in parts) be replaced by Pierre's patch from

Minor nit: By setting initialized to true, you rely on the previous
initialization of is_tcg to false for subsequent calls.
You could make this more obvious by saying:
return is_tcg;
Have a look at Pierre's patch which I will be relying on when it's done.
As I said in the commit message, this is only a placeholder for his patch.
