Take a look at LuaLanes ( https://github.com/LuaLanes/lanes ); it has a few C
functions to copy from Lua state to another.
(In fact, it may do exactly what you want your module to do: multiple Lua states
in separate threads with simple communication).

There's also my deep copy function, which you can find on lua-users (
http://lua-users.org/wiki/CopyTable ); although it is Lua-only, so you'll have
to find a way to convert it.
