Technically it does, because the statusline is printed as a single call to write, but I agree that's fragile and one could argue that works by accident rather than by design. I really like the idea of introducing an RAII object as it (1) makes the locking more explicit and (2) makes it easy to do the right thing and hard to do the wrong thing.
