    Let nyx shut down faster
    
    Especially when first starting up nyx takes a couple seconds to shut down on my
    relay. This is because the update method of our connection panel can take a
    while if there's many relays. Aborting in the middle of its longest part if the
    thread's terminated. This drops our shutdown time in practice to a few
    milliseconds.
