It seemed a bit odd (from the Apple guy's explanation) that only OS X was
affected, you'd think that either (a) all OSes would experience terrible write
performance or (b) all OSes would experience corruption.  Instead, depending
on whether you use FSSYNC or not, it's only OS X that gets hit.  Very odd.
