I got 100% rejects against this because Christoph has already had
his paws all over the slab constructor code everywhere.
Was going to fix it up but then decided that we ought to make changes
like this to ext4 as well. Ideally beforehand, but simultaneously is
OK as long as it's simple enough.
btw, for a benchmark I'd suggest just a silly create-10000-files
tight loop rather than something more complex like postmark.
