   One other good thing:   
      
   After my last major reorganization of the block headers, while there may   
   be sixteen different header types, now each header begins with one of the   
   following six bit patterns: 1101, 111001, 1110100111, 1100101001,   
   110010100001, or 111000101111, none of which begin anything that is not a   
   header in the basic instruction set without headers.   
      
   This means that logic to detect if a block starts with a header ought to   
   operate reasonably quickly.
