Is it just me or has this post disappeared? Here’s a screenshot:

Here too. Maybe the discussion thread locked the main body thread ;)

I've no idea where this went. Let me reach out to support

Thank you, really nice article.

[Antonio Alberto Lobato]

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

[Antonio Alberto Lobato]

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.
