Chris, > Have a method to explicitly purge the instance.
I was thinking of that too but decided against it, as it would mean that my objects would need to be handled specially - which is not quite what I'm looking for. To be honest, I was thinking of/hoping that there would be a method which was called when an objects reference count was changed.
