I think it is also not sufficient. This patch seems to cover only objects. But we assume that we can atomically rename() new versions of files into place whenever we like without disrupting existing readers. This is the case for ref updates (and packed-refs), as well as the index file. The destination end of the rename is an unlink() in disguise, and would be susceptible to the same problems.
