Nodes That Erase Messages

I'm sorry, Colin. I didn't mean any criticism of your comment.

I'm a great fan of the link node feature and was disappointed to see a possible flaw in its design. We don't yet know how serious the issue is or how many contributed nodes might need fixing. There may be ways to avoid having to test or inspect lots of contributed nodes or even ways to modify the NR core that will help.

Its ok, I didn't take it as critisism.

It is a weakness in the link-call feature, but it is difficult to see an alternative. I don't think it would be easy to implement some sort of stack equivalent, which would be the ideal, as there is a possibility of messages in the called flow to overtake each other so the order out might not match the order in.
