    application: Spawn the miners only when a window is created
    
    Creating the miner proxies during startup would spawn the processes
    even though they are only used when an application window is shown.
    This is bad because the startup is shared between the application and
    the search provider, and we should not needlessly spawn so many
    processes for each gnome-shell search.
