Marc-Andre Lemburg recently released a new version of
mxProxy. It supports weak references and thus allows for
circular structures (with a somewhat unintuitive behaviour
when the root element is released while references to
internal tree nodes are hold, like "weakdicts").
I expect changes to be rather local, when mxProxy should
be used.
