I don't exactly understand why your reply with this Windows story to the
fsyncobjectfiles paragraph. But if you think that fsyncobjectfiles+msysgit
is your killer argument, then you think wrong: fsyncobjectfiles is ignored
in msysgit. (We don't yet have an implementation of fsync() :-( )

The issue that Linus mentioned happened when a Linux client operates in a
repository that lives on a CIFS mount.

It will work with the caveat you mention. I have such a setup myself.
