Just a small aside from the main topic.
Not saying we should use traces here, but that statement worries me. I
proposed in the past we should add the concept of "signal" to ns-3, to which
you argued that traces an fulfill the same role, and I did agree with you.
Now you are saying traces cannot have side-effects. Well, in my code I
have been using a lot trace callbacks with serious side-effects (e.g.
searching for a new AP when the wifi signal is lost). So, make up your mind
already about the role of tracing...
