I'm not sure that fsync-on-FD after the rename will work, considering that
the issue here is that somebody might've unlinked the file altogether
before we get to doing the fsync. I don't have a hard time believing that
that might result in a failure report on NFS or similar. Yeah, it's
hypothetical, but the argument that we need a repeat fsync at all seems
equally hypothetical.

Mmm. That makes it easier to consider changing its API.
