Ah okay, now I see it in the manpage too. But it's in the BUGS
section. Can't we have a sync that stalls the system until its
buffers *really* are clean? I mean what kind of guarantuee does
the user have so that's safe to remove whatever media? triple-sync?
how is that better than one-sync? You have no guarantuee whatsoever...
