Thanks!

I do not know python, but it seems that with this patch we can kill g or t?
Can't

	def task_lists():
	    task_ptr_type = task_type.get_type().pointer()
	    init_task = gdb.parse_and_eval("init_task").address
	    t = init_task

	    while True:
		thread_head = t['signal']['thread_head']
		for thread in lists.list_for_each_entry(thread_head, task_ptr_type, 'thread_node'):
		    yield thread

		t = utils.container_of(t['tasks']['next'],
				       task_ptr_type, "tasks")
		if t == init_task:
		    return

work?
