Hi all,I would like to implement a 'thread pool' of Lua states (allocated with lua_newthread); what do I need to do to an existing lua State to clean it up before returning it to the pool?I figured at least lua_settop(L, 0), but what googling I have done also mentions that I should be careful about exceptions/errors in a state; but no more information could be found. What do I need to do?grrr waaawww.grahamwakefield.net
