m_config泄露了
从light ud改成ud之后，我期望是lua gc管理，但是泄露了

我觉得问题在于new和delete，这对应构造和析构，必须执行，不只是释放掉本身的内存
所以delete m_pConfig一定要调用的
所以这里要用到lua的__gc来finalize

直接delete也是不对的，会出比较底层的错误，没有任何有意义的错误信息
应该是要重载new和delete的，去学一下怎么搞

这个语法叫做placement new，我们现在的gc的情况就是典型用途之一
问题在于我们应该怎么析构
答案是不需要那么复杂，我们直接调用析构函数即可
m_pConfig->~T();

但是日后应该放到lua __gc中，由lua控制
