Question - Running multiple Luas

[Soandso2]

As I understand it, I can run multiple Lua scripts simultaneously. Do they execute in sequence, in some sort of loop? First script 1, then script 2, then script 3, then back to script 1 again and so on and so forth. Or do they execute in a parallell way? If the latter, does that mean that I can get faster execution of certain pieces of code?

Say that I have one Lua with an eternal do-while-loop, in which I call two functions. The second one wont execute until the first one is done. Granted this may only take milli- or micro-seconds, but still...
If I instead make two Lua scripts, each with an eternal do-while-loop and just call one function (in the loop) per script. Does this save me time (again possibly micro-seconds, but again... still)

Consider each Lua to be a self contained, self aware process. LuaA does not know about what LuaB is doing.

Alright. So do not clog Lua 1 with non-Lua-1-related stuff. Thanks.
