How about that?

Another things are implementation details.

And I'm not sure the following sentence is needed.

I think it may assume global variables. But this API is independent from
C's global variables. I think this comment may be for
`rb_global_variable' users, but it is different API.


PS.
For our MVM development, we can not support "rb_global_variable()". So I
want to make it obsolete.
This is why I introduce rb_gc_register_mark_object(). But not yet.
