Enumerator uses Fiber to keep a control flow in internal.

Now thread local variables are fiber locals.  I agree it is confusing.
But I'm not sure how to solve it.

One idea is:

  - Define: Thread#[] -> Thred#current_fiber#[]
  - Add: Thread#truly_thread_local_get(key)
    and  Thread#truly_thread_local_set(key, val)

(of course, truly_... is temporal name)
