Hi, thank you for the explanations. I had overlooked the cyclic nature of what I had produced here and, of course, the GC can't be blamed for not collecting objects that are part of a cycle. The other question about the last refe- rence to an object vanishing within a method call (which, as I now clearly understand, can't happen and wouldn't make much sense) was triggered by a segmentation fault I get when I do something similar in PySide, so I was getting worried if it might be due to a GC issue. Now I know its got to be something different;-)
