    After changing the parameter from `NotSerialized` to `Serialized`, the
    remark is indeed gone and there is no size change.

    The remark was added in ACPICA version 20130517 [1] and gives the
    following explanation.

            If a thread blocks within the method for any reason, and another thread
            enters the method, the method will fail because an attempt will be
            made to create the same (named) object twice.

            In this case, issue a remark that the method should be marked
            serialized. ACPICA BZ 909.
