I mean when I Close a lua_State L, can I know all coroutine of L, then 
     void ClearScriptFile(string file)
     {
         itScript it = m_mapScript.find(file);
         m_mapScript.erase(it);
        L = it->second;
        //for l  in coroutines of L  , close l, remove timer of l 
         lua_close(L);
     }
