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

[gary ng <garyng2000@...>]

Hi,

Since lua don't have thread support out of the box,
the alternative would be spawning multiple small lua
process if I want some form of multi tasking(I know
there is coroutine but let's say that coroutine
doesn't fit the scenario).

How would I have a simple efficient way of
bi-directional communication between two lua process ?
On, unix platform, using domain socket seems to be
easiest(though I am not sure if luasocket supports it
and I was told that there is no such a thing on
Windows). popen() only creates a one way pipe.

Or must I fallback to the 127.0.0.1 interface ? I see
two problems with that, security and unnecessary
payload(the network layer). Though it has the
advantage that it is network ready by design.

What I want is a relatively portable way(mainly *nix
and Windows) for this need.

regards,
