If it's something you can solve without worrying about block-level
writes and whether the underlying drive (if indeed there is even a
"drive") has a battery-backed cache or sufficient capacitor charge to
write your data, I'm all for it.  Even better if it's POSIX.

Although a block driver and other filesystem-bypassing solutions may
be interesting in limited cases, I'd rather not see anyone stab their
wife over it.
