Exactly. In my case (and I suspect also in many other simple GUI apps)
there is no data parallelism, it's all about glueing together blocking
method calls while preserving some kind of responsiveness to additional
events. It's not nice, but writing from scratch is not attractive
either.

I have written multithreaded code for over 20 years; trust me, I know
the pitfalls.
