Note that the StoredObject this ValueWrapper is created with is unretained so it must be used
before the owner of the StoredObject releases it. Since the RegionEntry that has the value we
are writing to disk has it retained we are ok as long as this ValueWrapper's life ends before
the RegionEntry sync is released. Note that this class is only used with uncompressed
StoredObjects.
