Great, thanks!
One note: without Thread.new around the first loop this code could not ever run both loops in parallel, even if MRI had no GIL. Maybe a typo.

I think it's not a type, the main thread is also a thread

Of course, the main thread is a... thread, but how that matters for the issue?
Any line of code that runs synchronously forces the next line to wait. So, we need a Thread.new, just to let the interpreter to reach the next line while the first one is running.
