+# After creating an PyObject that inherits from QObject, connecting it,
+# deleting it and later creating another Python QObject-based object, this
+# new object will point to the same memory position as the first one.
+
+# Somehow the underlying QObject also points to the same position.
+
+# In PyQt4, the connection works fine with the same memory behavior,
+# so it looks like specific to SIP.
