    tests/monitor-unit-tests: Sleep some after each hot plug
    
    Give clients (such as Xwayland) a chance to bind the wl_output global
    before we continue, otherwise there is an significant risk that mutter
    won't see the bind request until after the next hot plug which might
    have destroyed the global object.
