I don't think we will get to choose. The alternative will be to switch
to some other language that does provide threading. But let's not get
into this discussion because I believe it is not relevant to the problem
at hand.

AFAICT, none of what he did is done because of preemptive threading.
IOW, I don't think you can do it much more simply, even if you assume
a cooperative threading model.

I don't think this is "only needed for preemptive thread scheduling".
