    Disable accessibility
    
    Accessibility prevents sysprof from working reliably, so disable
    it. Specifically, it
    
    - causes large amounts of time to be spent in sysprof itself
      whenever the label is updated.
    
    - sometimes hangs at shutdown
    
    - does long-running roundtrip requests that prevents
      reading the event buffers, resulting in lost events.
