 *

 * Purpose: Manage priority queues of free-lists (of blocks of bytes).

 *      These are used in various places in the library which allocate and

 *      free differently blocks of bytes repeatedly.  Usually the same size

 *      chunked data for example, but the blocks may also be of different sizes

 *      from different datasets and an attempt is made to optimize access to

 *      the proper free list of blocks by using these priority queues to

 *      move frequently accessed free lists to the head of the queue.
