SetPipelineInformation will cause the information object to increment the
reference count of the data object. Thus calling Delete will safely
decrement the reference count without yet releasing the memory (this matches
the reference created by NewInstance()). This is necessary or else a
reference will be floating and the object will never be deleted.
