* @class TP_Servant_State
*
* @brief Maintains state information for a particular servant.
*
* This TP_Servant_State class is an intrusively reference-counted
* class. This allows it to be held in a "smart pointer" (aka, handle)
* object that will manage the reference-counting automagically.
*
* One TP_Servant_State object is created for each servant object for
* which a request is to be dispatched. The servant state objects are
* held (via smart pointers) in a TP_Servant_State_Map object. In turn,
* the TP_Servant_State_Map object is a data member of the TP_Stategy
* class. Each request placed on to the request queue will hold a
* reference (via a smart pointer) to the servant state object.
*
* Currently, the only "state" info held in this TP_Servant_State class
* is the servant's busy flag.
