This requires Ben's work to decouple the ext2 allocation size from the
hardware page size. We would _always_ want to write out a fragment block
as one to ensure that the fragment descriptor wasn't at odds with the
contents of the block. Imagine the descriptor not being written out after
the block was compacted.
