I think this has been fixed by another CL (sorry for typo...)

I needed this in order for the test to pass. rebased.

       delete activities_.front();
 
     CHECK_EQ(this, instance);
     instance = NULL;
   }
 
   // ActivityManager:
   virtual void AddActivity(Activity* activity) OVERRIDE {
     CHECK(activities_.end() == std::find(activities_.begin(),
                                          activities_.end(),
