Thanks @StephanEwen and @uce for looking into it! I really appreciate it.
How about the following:
1. I update this PR with the patch that uses ListState and apply some nice
refactorings Gyula made
2. I will also address all your comments and then merge this to master
3. We start working on perfecting stream finalization on loops and
backpressure deadlock elimination in seperate PRs right away. These are
different problems and we need to address them separately, in my view of course.
