I like your approach and in general I do the same. But some interrupters just never learn.

So in some cases when the interrupter keeps interrupting I simply ask him/her: "Can I finish my sentence?" In this case whatever the interrupter does it's too late for him, because it becomes obvious that his way of communication is not welcome and he was not even aware of this fact (i.e. he lacks self-awareness), and learning self-awareness in a group setting this way makes wonders.

Also I guess you make small refactors instead of reactors :)
