Uh, both please :)

I think[1] Octave misses an fsync() somewhere in its code (at least I
couldn't find one). The easiest place would be in the code for unlink(),
but that would also be the biggest penalty. However, doing it on exit
should be okay performance-wise.

[1] I might be wrong, of course. I'm not that deep into filesystems and
race conditions.
