Read a little more on the structure of the BSD file system.  While the major
allocation segment is 8K, the BSD file system has a fragment block for
the last segment of a file.  The size of this block is also configurable,
but it is usually on the order of 1K.

So a file system with thousands of small files will eat up thousands
of 1K blocks (just like in the 1K system V file system).
