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