Close is used to close a DataInterfaceStream module. This happens automatically when this object is garbage collected; however, you can call Close to release the resources earlier.

Any descendant modules of stream are closed when stream is closed.  (A module is a descendant of a parent module if it is returned by one of the parent module's exports or if it is a descendant of one of the parent module's descendants.)
