Your step to reproduce successfully shows an example that really could run multithreaded without having to worry about anything. Atleast the part inside the onEachFrame handler, and that also only in theory.
But.. Your code is also useless and essentially does nothing. So your example is that Nothing could actually be run multithreaded. That's true. Just spawn 1000 Threads that do nothing. Why though?
What you suggest here will never come to A3.

This is completely trolling post,
the code shows inability of Arma 3 to process code in multiple CPU' threads,
that code is to prove existence of issue, and have no requirement to do anything,
its up to Arma 3 dev. team decisions of functionality implementations

You may think that dedmen is trolling you but this is just a validation that you have no real clue what you are writing in this task. This code exactly shows nothing what is related to your proposal. Plus, your whole task is a duplicate of a duplicate of a duplicate. If you think that you are the very first person that is proposing this you're definitely wrong.

If you are breaking your frames with your scripts then you are doing it wrong. If you are implementing your code snippet to another programming language like C# or Java you are going to freeze the whole process.

Tired of answering pointless posts;
For moderators: The proposed as duplicate ticket describing problem, this one describing support for functionality which on 1 side directed on solution of the problem.
