So it's more like the way NFS treats syncs. Eventually... :-)
} I will add this option before 1.9.18p9 ships - the only

Sounds to me like there are two issues. One, to make the
behavior consistent with NT's, perhaps only flush the stream.
But then, what if somebody _really_ wanted a sync done when
SMB says to do one? Is that two options?
