frame_event_publisher and loop / high cpu

I’m seeing high cpu use and even unusable pages with some pages with iframed iframes and the Nextgen gallery frame_event_publisher.js. This seems to keep going and going in this part of the code, quite wasteful:

setup_ajax_handlers: function() {
    if (!this.ajax_handlers_setup) {
        var publisher = this;
        jQuery(document).ajaxComplete(function(e, xhr, settings) {
            setTimeout(function() {
                publisher.ajax_handler();
            }, 0);
        });
    }
},
