     22  * The object registry manages a collection of global singleton objects.  However, it differs from
     23  * the standard singleton pattern in a few important ways:
     24  * - The objects managed by the registry have an undefined lifetime.  They may become invalid at
     25  *   any time, and they may not be valid at the beginning of the program.
     26  * - The only object that is always guaranteed to be valid is the ObjectRegistry itself.
     27  * - There may be more than one ObjectRegistry, and there may be more than one instance of any of
     28  *   the systems managed by ObjectRegistry allocated at once.  For example, separate threads may
     29  *   maintain their own separate ObjectRegistry instances.
