Here it is. Several patches are unchanged (fetched from Junio's tree and
reposted). There are two new patches (5, 12) to address some similar or
related issues noticed by Peff and Junio.

I think this got better by getting rid of `CLOSE_LOCK` entirely instead
of playing with `HAS_SINGLE_BIT()`. Patch 11 also improved IMHO by
squashing patches 10-11 of v1 and presenting the issues a bit
differently in the commit message. Thanks for your feedback, both of
you.
