The question still reamins about link/unlink/rename.  Is a fsync of the
directory necessary to ensure that they completed properly?  As they take
filenames instead of fds, an fsync after the operation seems
non-intuitive.  The rename manpage seems to imply that the operation is
synchronous - the other two are ambiguous.
