But have you tried creating one thousand of OS threads and measuring the actual memory usage? If I recall correctly I read some article where it was explained that threads in Linux are not actually claiming their 8MB each so literally. I need to recheck that later.

You're right, I've read the same. Using Python 3.8, creating 12,000 threads with `time.sleep` as the target clocks in at 200MB residential memory.
