    You are correct, so the check is not necessary, but I think it would still
    be good to use the macro because double-deleting a pointer is still not ok.
    Using DELETEP(ptr) twice is fine. Then again, deleting from two independent
    (unrelated?) places usually means there's an ownership problem.
