How to use the etch.setScheduler function in etch

this.disposables = new CompositeDisposable();
    this.session = session;

    // Load the Fit Addon
    this.fitAddon = new FitAddon();
    this.session.xterm.loadAddon(this.fitAddon);
    this.disposables.add(this.fitAddon);

    //
    // Observe the Session to know when it is destroyed so that we can
    // clean up our state (i.e. remove event observers).
    //
    this.session.onDidDestroy(this.destroy.bind(this));

    // TODO: Documentation says this should be set for Atom... Research!
    etch.setScheduler(atom.views);
    etch.initialize(this);

    this.observeResizeEvents();
  }
