##### No, once an Object reference is added to the session, with putValue,
retrieving that reference does not remove it from the session, so calling
putValue after modifying the Object is not required.

##### valueBound will be called each time the putValue is called, but since
it is only necessary to call putValue once, that should not pose a problem.
valueUnbound is not called for a getValue.
