No terrible bugs until now on my test.

My current idea for next week is following.
(I may have to wait until the end of next merge window. If so, 
 I'll wait and maintain this set.)

 - post ready-to-go set again.
 - post 1/6 and 2/6 as may-ready-to-go set. I don't chagnge order of these.
 - reflects comments for 3/6. 
   patch 3/6 adds new functions. So, please tell me if you have better idea
   about new functions.
 - check logic for 4/6.
 - 5/6 and 6/6 may need some more comments in codes.
 - no new additional ones.


Thanks,
-Kame
