Hi Josh,

Thanks for the reply. I was looking over the YARV implementation in 1.9.3rc1
and did notice some support for pthreads and ruby threads (and some
description in the comments of certain models). Do you know if (or does
anyone else) if this code is fully implemented at present? Or is it a global
lock like situation?

Regards,

Carter.
