So it still consumes 8 MB of address space though? On a 32 bit system that would severely limit the number of threads you could allocate in each process wouldn't it? How do you allocate 8 MB of stack times a hundred thousand, in a 32 bit address space?

Yes, it breaks on 32bit but that's an acceptable tradeoff in most places because the vast majority of places where a modern language like swift would actually be used are 64bit.

The person I was replying to asked where the 'myth' came from. It came from 32 bit systems, where it isn't a myth. Even if it doesn't apply today (and administrating thousands of pages per thread still isn't free even if you have the address space, so I'm not sure it doesn't still apply really), that's where the 'myth' came from - that's the answer to their question.

What 32-bit systems even exist anymore? Much less 32-bit systems where you want to run thousands of threads in a single process?

The question was 'where did the myth come from' not 'does it still apply today'.
