Untrue. Objects and attributes may be shared by threads so attribute accesses can't in general be localized.

It is true! If you explicitly synchronize between threads, sure, you can't optimize it in general, but if not, the compiler is well within its rights to cache the access.

Sure, if the compiler can prove that the objects are thread-local. But that's not the general case.
