When there is no load but there are zombies to be cleaned up, it used to take at least nthreads*timeout time to get socket closed. Now in this case, once the timeout exceeds for the first time, all threads are allowed to call dcb_process_zombies without having to wait the timeout period until there are no zombies anymore.
