Does that mean functions like (replace-string) should now be rewritten
to yield time? Or are they already written like that? Will or did that
slow them down?
Or does it mean someone writing a function should always write it so
that it yields time, accepting that it might be slowed down?

Shouldn't threads that are just waiting yield time to others
automatically?
When I use Term::ReadKey in perl to read a key, my program can be
waiting for a key to be pressed without using CPU time. It does that
automatically.
