However, what both of us were talking about won't run into this problem.
We were not going to share data and have a concept of "multiple-lua"
threads. We effectively just want to be able to instantiate multiple
copies of the "lua environment", each in it's own thread, but completely
separate. 

While it would be nice to include all of this functionality into Lua, I
don't have any immediate need for multiple threads within one global lua
space.
