I did not have any problems using lua from multiple threads
on a multi-cpu machine running windows .
The interface was implemented using the excellent 
luabind library.

You must make sure that a single luastate (and therefore
all the calls that use luastate) is not used by multiple threads
at the same time, in my instance, each thread on startup was setup
to have a luastate.  So the same luastate would be used by only that

So 5 threads, 5 luastates that are permanently attached to each thread.
