you also might be interested to have a look at
- lua-llthreads2  - Low-Level threads for Lua
- mtmsg  - Low-level message buffers for inter-thread communication
- mtstates  - Pass Lua states to other threads
- mtint  - Make threads and coroutines interruptible
These are orthogonal and low level cross platform packages that can be combined
and play well together. IMHO they build a simple and minimal base for building
higher level multi threading constructs in pure Lua.
