Release an object obtained from the workflow service immediately instead of waiting for it to be automatically released. This may be called to optimize resource utilization.
We do not want to define a specific mechanism for implementing the remote invocation mechanism used with the workflow API. Therefore, we cannot demand that each object defines a method to release resources (like e.g. CORBA's release). This method knows about the implementation specifics and acts appropriately.
@param obj the object which is no longer used.
