Oops, this patch breaks

        /* For concurrent nodes setup, we allow only one to continue */
        while (zk_member_empty() && zk_master_create() != ZOK)
                ;/* wait */

I guess this was why in the old code I chose to panic(). Now when I
start 3 node concurrently, I'll end up with 3 nodes are all master.
Unless we find a solution, this patch will be reverted.

Thanks,
Yuan
