Yeah -- unless we're prepared to drop threadless systems altogether,
this doesn't seem like it does much for maintainability. It might even
be a net negative on that score, due to reducing the amount of testing
the now-legacy code path would get.

If there were reason to think we'd get a large performance benefit,
or some other concrete win, it might be worth putting time into this.
But I see no reason to believe that.

(There's certainly an argument to be made that no-one cares about
platforms without thread support anymore. But I'm unconvinced that
rewriting existing code that works fine is the most productive
way to exploit such a choice if we were to make it.)
