Can we just weaken the references with Scalar::Util? This should
solve the problem for circular refs. Is Scalar::Util part of the
core distro in the min perl we are supporting?
I can add this in Bio::Tree::Node and look around to see where else
it is a problem. We just need a simple script to verify it is having
an effect (i.e. a bug report with this).
