This is what I said is the disagreement in the WG.  I can pull up the 
old email chain if needed, but I think others can too.  One side was 
arguing that there's no such guarantee and you need to do a WIN_SYNC to 
see the value.  The other side was arguing that the WIN_SYNC should not 
be needed; FLUSH + SEND on the origin should be enough.
