+Exercise the behaviour of 'self' in Interpreter Embedded Python.
+
+So far it wasn't possible to tack an attribute to self, and have it
+retained across several calls (basically using self.attr as extension
+of _setup on the Python side).
+
+This test shows that attributes on 'self' were not retained across calls.
+A following patch will fix this.
