Now I merged the first two patches, as they are safe and good fixes. The patches 3 and 4 are still pending, although I'm inclined to take them for now. Someone might have a better idea without the extra base ops change. In anyway, the patch 3 can be a bit simplified; the extra NULL initialization is superfluous, so you can drop those lines. Oh, BTW, at the next time to submit a patch set, please try to keep the threading. Usually git-send-email creates thread automatically when you send the whole patches in a shot. Takashi
