13      * When the POA has the NON_RETAIN policy it uses servant
14      * managers that are ServantLocators. Because the POA
15      * knows that the servant returned by this servant
16      * manager will be used only for a single request,
17      * it can supply extra information to the servant
18      * manager's operations and the servant manager's pair
19      * of operations may be able to cooperate to do
20      * something different than a ServantActivator.
21      * When the POA uses the ServantLocator interface,
22      * immediately after performing the operation invocation
23      * on the servant returned by preinvoke, the POA will
24      * invoke postinvoke on the servant manager, passing the
25      * ObjectId value and the Servant value as parameters
26      * (among others). This feature may be used to force
27      * every request for objects associated with a POA to
28      * be mediated by the servant manager.
