How to ensure discarded thread is GC'ed?

[jrivett@...]

Hi, 

I've recently added LUA to our game project and wrapped everything up in a 
couple of C++ classes. 

Each time a new script is needed the function below is called, creating a 
new thread (CScript object) with new global table. 

My question is: How do I ensure a thread is garbage collected once 
discarded? 

i.e.
	delete pMyScript; 

CScript::~CScript(void)
{
	// what to do here?
} 

Thanks in advance, 

Jamie 





CScript *CScriptManager::NewScriptFromFile(const char *pFilename) {
	lua_State *pState = NewLuaState();
	CScript *pScript = new CScript(pState); 

	.
	.
	. 

	return pScript;
} 

lua_State	*CScriptManager::NewLuaState(void)
{
	lua_State *pState = lua_newthread(m_pBaseLuaState); 

	lua_newtable(pState);	// new table for globals 

//	this does the LUA equivalent of: setmetatable( {}, { __index = _G } )
	lua_newtable(pState);	// metatable for new globals
	lua_pushstring(pState, "__index");
	lua_pushvalue(pState, LUA_GLOBALSINDEX);
	lua_settable(pState, -3); 

	lua_setmetatable(pState, -2); 

	lua_replace(pState, LUA_GLOBALSINDEX); 

	return pState;
}
