Actually I think the root of the problem was precisely that Linux does not
issue any sort of cache flush commands to drives on fsync. There was some talk
on linux-kernel of what how they could take advantage of new ATA features
planned on new SATA drives coming out now to solve this. But they didn't seem
to think it was urgent or worth the performance hit of doing a complete cache
flush.
