/**

 * based -- ensuring grouping by host -- terminated by a zero
 * byte. Then 8 bytes of data ensuring desired ordering 
 * within that 'queue' are used. The first byte of these 8 is
 * priority -- allowing 'immediate' and 'soon' items to 
 * sort above regular. Next 1 byte is 'cost'. Last 6 bytes 
 * are ordinal serial number, ensuring earlier-discovered 
 * URIs sort before later. //from   w  ww .ja  v  a 2 s  .  c  o m
 * 
 * NOTE: Dangers here are:
 * (1) priorities or costs over 2^7 (signed byte comparison)
 * (2) ordinals over 2^48

 * Package access & static for testing purposes.
