The fact that we live in multiple thread environments does not mean that we have to use them.

The same could be said about Internet, people say "there was no Internet distractions" when you could disconnect the network in any computer with a 3 seconds click.

In fact what threads do is make your life easier. I did program a multimedia program in DOS using INTs and it was the definition of hell.

Now you could make a simple audio thread, another simple picture animation thread and the more complicated thing you deal with is managing mutexes, that is super easy if you understand them.
