Not tested (maybe we cannot pass a NULL callback):

    struct event *to = NULL;
    do {
       if (event_base_got_exit(base) || event_base_got_break(base)) break;
       if (to) event_free(to);
    
       /* Do your global stuff here. */
    
       struct timeval one_second = {1,0};
       to = evtimer_new(base, NULL, base);
       event_add(to, &one_second);
    } while (event_base_loop(base, EVLOOP_ONCE) == 0);
    event_free(to);

Either there is nothing to do and an event will be triggered by the one
second timeout or there is something to do and you cancel the timeout.
