but as I tried to explain, the new behaviour of CommonTreeNodeStream
is that its contents are discarded as they are accessed by the tree
walker, so you can reset the stream but there's nothing there anymore
I don't like this at all, but I believe in the thread that you cited
earlier someone says it is the intended behaviour.
