What about for fsync(2)? One of the most frequent sources of data loss on the
postgres mailing list has to do with users with IDE drives where fsync returns
even though the data hasn't actually reached the disk. A power outage can
cause lost data or a corrupted database.
Is there any progress getting fsync to use this new infrastructure so it can
actually satisfy its contract?
