26 * The entries in a delta index could be stored in a single delta list, but to reduce search times
27 * and update costs it uses multiple delta lists. These lists are stored in a single chunk of
29 * memory, so the location of each delta list is recorded as a bit offset into the memory. Because
30 * the volume index can contain over a million delta lists, we want to be efficient with the size
31 * of the delta list header information. This information is encoded into 16 bytes per list. The
32 * volume index delta list memory can easily exceed 4 gigabits, so a 64 bit value is needed to
33 * address the memory. The volume index delta lists average around 6 kilobits, so 16 bits are
34 * sufficient to store the size of a delta list.
36 * Each delta list is stored as a bit stream. Within the delta list encoding, bits and bytes are
