Re: simple and efficient way to have bi-directional communication between lua process

[Asko Kauppi <askok@...>]

You don't need to dive into OS specific issues, at all. Threads share  
a common address space, so all you have to do is serialize Lua data  
structures into a stream (allocated char array), deserialize it in  
the other thread. I would definately see a need for this + basic  
thread creation (portable) + lazy evaluation, all together in an easy  
to use package.

DBUS, sockets etc. can be done using similar approach, but they'd be  
useful only if
- communicating with existing non-Lua services
- communicating across process boundaries (another CPU)
