If I walk down the tree and memorize a well-identified set of nodes, and later try to compare the results of a findChildren() call to those well-known nodes, I realize they do not match, despite .blink() really showing the same (text entry) widget:

- the objects do not have the same id(), which is surprising in itself, showing that there is a waste of RAM by object duplication, so 'a is b' does not work
- 'a == b' does not work either

Maybe __cmp__ could be implemented for Node objects, so at least 'a == b' can be used, but it would seem much better to me to avoid the duplication of objects in RAM (although that might be an issue in python-atspi or even in atk).

Even if fixing an underlying lib is the best long-term solution, it may be useful to implement __cmp__ so dogtail can work with any version of the to-be-fixed lib.
