Saving a refcount bump is not worth the churn. Use a proper RefPtr<> everywhere instead of manual refcounting, and don't make DoSheetComplete call NS_RELEASE unconditionally. Also, make clear by using references where null is expected or not. Also, properly use a RefPtr in mPendingDatas, since they are strong pointers, in fact. Finally, remove some unused macros from nsCSSValue of which this code was the last consumer.
