I knew that for msdosfs; that's one of the reasons I asked. Given the
limits on our USB driver, though, it isn't clear to me that our ext2
performance is the limiting factor...
More seriously -- for this particular application, I don't think
performance issues are critical. I'm much more concerned with stability
