Keith, should the standard include an example of UNIFIED that is
portable, but does not call MPI_Win_sync?

If so, what memory model should be assumed?  (C11 seems like a likely
candidate, though I think the best quality documentation on these
affairs is associated with the Linux kernel, and is readily implemented
without language extensions.)
