I think we'll have to support non-blocking/event-based waitpid
in Windows for auto-fiber/Thread::Light, anyways.  So making
MJIT worker thread be a Ruby Thread (or Thread::Light) would
allow it to hook into process.c APIs.  I don't think the
existing code is too far off from being able to support
Windows...
