       The old setup wastes most of  this  bitmap  page,  because
       zero  bits denote bad blocks or blocks past the end of the
       swap space, and a simple integer suffices to indicate  the
       size  of the swap space, while the bad blocks, if any, can
       simply be listed. Nobody wants to use a  swap  space  with
       hundreds of bad blocks. (I would not even use a swap space
       with 1 bad block.)  In the new style  swap  area  this  is
       precisely what is done.  The maximum useful size of a swap
