I have no idea to achieve your issue.

Seeing other environment:

- Python: there is no priority on Thread.
- Perl ithread: OS dependent priority.
   (not affect on most UNIX environment)
   (on Windows environment, we can use priority)
- C, C++'s native thread: ditto.

(Please point out if you find mistakes)


There are 2 options:

1. This is Ruby's good point, so we must support
    OS independent exact thread scheduler
    (with development/running cost).

2. We don't need such big mechanism on thread because
    other environments don't support it.

(optional-3: we should choose 1 or 2 on build/launch timing)


Any comments?
