--- Comment #10 from Paolo Carlini <paolo.carlini at oracle dot com> 2011-09-02 10:41:52 UTC --- (by the way, if you can see a neat enough way to improve _M_are_all_aux, you are welcome to propose it! I'm definitely not an expert in this area, and when I implemented it, I remember just quickly hacking something close to what we have elsewhere, which I could easily convince myself was correct)
