nit: could use a blank line

This class and it's method are pretty vague in its meaning. In your usecase, you
really want to know when the set of running workers has changed, is that right?

class Observer {
  virtual void OnRunningWorkersChanged() = 0;
};

I think additional methods could be added for what vincent is working on.
