3.0.2版的msh中，执行list_event时死循环。

static long _list_event(struct rt_list_node *list)
{
    int maxlen;
    struct rt_event *e;
    struct rt_list_node *node;

---->    maxlen = object_name_maxlen(list);    在这个函数里死循环了。

rt_kprintf("%-*.s      set    suspend thread<br>", maxlen, "event"); object_split(maxlen);
    rt_kprintf(     "  ---------- --------------<br>");
    for (node = list->next; node != list; node = node->next)
    {
        e = (struct rt_event *)(rt_list_entry(node, struct rt_object, list));
        if (!rt_list_isempty(&e->parent.suspend_thread))
        {
            rt_kprintf("%-*.*s  0x%08x %03d:",
                       maxlen, RT_NAME_MAX,
                       e->parent.parent.name,
                       e->set,
                       rt_list_len(&e->parent.suspend_thread));
            show_wait_queue(&(e->parent.suspend_thread));
            rt_kprintf("<br>");
        }
        else
        {
            rt_kprintf("%-*.*s  0x%08x 0<br>",
                       maxlen, RT_NAME_MAX, e->parent.parent.name, e->set);
        }
    }

return 0;
}
