    menu threaded test: run the mainloop after export
    
    GDBusConnection now dispatches GDestroyNotify calls back to the
    mainloop.  Adding an idle to the mainloop is O(n) in the number of idles
    already there.  We therefore need to periodically empty the mainloop to
    avoid quadratic behaviour with a very large 'n'.
