  Thanks Oliver, I like compromises. You inspired me to try another way: Out with the `unique_lock<mutex>`, in with the `unique_ptr<bool>`. This way no custom RAII wrapper is needed.
  
  OTOH, I'm not really convinced there is no threading involved (or will be in the future). Anyway, I hope this is acceptable now.
