Re: threading in lua 5

[Asko Kauppi <asko.kauppi@...>]

I'd just create two Lua states and use them from separate OS threads.

Assuming that:
- io.write() is thread safe?

You will need:
- ability to launch new threads
- inter-thread communications (if you care)

Does anyone know the thread-safeness of the Lua libraries?
