What is Lua Lanes?
Lua Lanes is a multithreading module for Lua 5.1 and Lua 5.2. Just like coroutines, but the best of it is that it does NOT freeze.

Here you see I've made a modified version of Lua Lanes that allows you to use the same function environment as the main Lua state, all the memory is shared between CS2D's Lua state and this Lua state. Here's an example of code.
IMPORTANT ADVISE: Memory accessing/writing must be managed with mutexes, using this module always exposes your server to a crash.

I like it!
Before using: call lanes.configure first(without any parameter)
(Hint for newbies)
Code:
1
2
3
2
3
lanes=dofile'lanes.lua'
lanes.configure()
-- Your code here
lanes.configure()
-- Your code here

VADemon: I meant when the main lua state is closed, the generated lua threads (coroutines) will remain in the OS threads that are running. I made a timer in a separate thread to test this and it resulted into a crash of the application (On CS2D, when I changed the map, the server's Lua state died but the threads were still alive thus the timer in them tried to access the dead Lua state).
