Looking at the results, ext2 is out because it isn't crash safe, and I
have heard Reiser uses a lot more CPU to do its work.  It does show
ext3 as slow, which was expected.  Interesting how JFS came out, and XFS
would be interesting.  And, of course, it is multiple backends that
really shows PostgreSQL off, so it could radically affect the results.
