I realized that there are two patches in this thread that are implemented according to different methods, which causes confusion. So I decide to update this thread with only one patch, i.e. the patch for 'Implementation 1' as described in the first email and then move the other patch to a separate thread.
With this idea, here is the patch for 'Implementation 1' that is rebased with the latest master.
