Originally, Gioh Kim had tried to support this feature but he moved so I took over the work. I took many code from his work and changed a little bit and Konstantin Khlebnikov helped Gioh a lot so he should deserve to have many credit, too. And I should mention Chulmin who have tested this patchset heavily so I can find many bugs from him. :) Thanks, Gioh, Konstantin and Chulmin!
