Hi,

My doctor thesis (sorry, written in Japanese) is work for removing GIL
(we call it GVL).  I concluded that with keeping compatibility with
current MRI, it is hard work to support parallel threads because single
thread execution will be slow down.

I recommend that Ruby should be encouraged that more course-grained
palatalization such as process level and so on. We will try to add this
feature after 2.0.

Thanks,
Koichi
