 * Data Structure overview
 *  There are 3 global Linked-Lists (LLs)
 *  pGlobalCBHead points to head of Command Buffer (CB) LL
 *    Off of each node in this LL there is a separate LL of
 *    memory objects that are referenced by this CB
 *  pGlobalMemObjHead points to head of Memory Object LL
 *    Off of each node in this LL there are 2 separate LL
 *    One is a list of all CBs referencing this mem obj
 *    Two is a list of all XGL Objects that are bound to this memory
 *  pGlobalObjHead point to head of XGL Objects w/ bound mem LL
 *    Each node of this LL contains a ptr to global Mem Obj node for bound mem
 *
 * The "Global" nodes are for the main LLs
 * The "mini" nodes are for ancillary LLs that are pointed to from global nodes
 *
 * Algorithm overview
 * These are the primary events that should happen related to different objects
 * 1. Command buffers
 *   CREATION - Add node to global LL
 *   CMD BIND - If mem associated, add mem reference to mini LL
 *   DESTROY - Remove from global LL, decrement (and report) mem references
 * 2. Mem Objects
 *   CREATION - Add node to global LL
 *   OBJ BIND - Add obj node to mini LL for that mem node
 *   CMB BIND - If mem-related add CB node to mini LL for that mem node
 *   DESTROY - Flag as errors any remaining refs and Remove from global LL
 * 3. Generic Objects
 *   MEM BIND - DESTROY any previous binding, Add global obj node w/ ref to global mem obj node, Add obj node to mini LL for that mem node
 *   DESTROY - If mem bound, remove reference from mini LL for that mem Node, remove global obj node
