Scratch is not multithreaded

(from the capabilities section)

I would like to note that Scratch is not multithreaded; Scratch runs one block at a time, that's why there are no race conditions. Stacks run in the order of when the hat block was pressed. Then every frame, one block is run per stack that is actively running, unless it's running without screen refresh. If it's running without screen refresh, it runs all those blocks in one frame instead of running them each one frame apart. This is actually what makes full/true transpilers pretty much impossible, there's no other programming language (besides Snap!) that executes code in this way.

Good to know. I hadn't looked too much into how scripts are executed, so I made the wrong assumption that several scripts running at once = multithreading. I'll remove it for now and elaborate more on how stuff runs when I add in the section for it.
