Lua equivalent to Python's Multiprocessing?
===

In some Redis loading tests, LuaJIT 2.0 (beta) is performing quite nicely, at about 60% of the runtime of a similar single threaded Python script.

When using Python's multiprocessing module to [chunk large text files](http://www.ngcrawford.com/2012/03/29/python-multiprocessing-large-files/), results in a significant performance improvement splitting the works across cores.

I am assuming using the same approach in Lua would perform even better, but as a Lua beginner, I have not found the correct approach. Can anyone point me in the right direction?
