Er. Yes. At least on ext4 this is pretty important. I wish it weren't,
but it doesn't look like we're going to convince the ext4 developers
they're crazy any day soon and it would really suck for a database
created from a template to have files in it go missin.

actually, as I understand it you need to do this on all filesystems except ext3, and on ext3 fsync is horribly slow because it writes out _everything_ that's pending, not just stuff related to the file you do the fsync on.
