afaic thread cannot be collected until it is in the LUA stack. Find
your thread in the LUA stack and remove it, later this thread will be
collected :

for (int i=1, n=lua_gettop(L); i<=n; ++i)
    if ((lua_type(L,i) == LUA_TTHREAD) && (lua_tothread(L,i) == thread)) {
       lua_remove(L,i);
       break;
    }

btw, this procedure _must_ be done and in case your thread is over,
since if you don't do this LUA stack will overflow with time.
