Quoting from there:
On the other hand, it cannot benefit from the existence of multiprocessors, because for this, kernel support would be needed. In practice, this is no problem, because multiprocessor systems are rare, and portability is almost more important than highest concurrency.

That is seriously crazy, in 2020. Is this just the docs that are not up-to-date, or is this really something that still works that way?
