Are you creating a new instance of the lua interpreter for each thread? 
 From what I understand, you need to create independent instances of 
the interpreter.  Most likely, you realize this and are doing so.  
however, there could be a conflict based on the snippet you have 
chosen.  What I would recommend is to write a small snippet that really 
doesn't do anything except open a lua script and grab a few variable 
values, and then print them to stderr or wherever you wish, and fork 3 
or 4 times and have it test this....once you succeed at that, you know 
it's not an issue with your lua calls.  However, if that fails, send 
another post with the code attached or whatnot for the simple test and 
we collectively can see where there could be a problem.
