How do I properly clean up resources when using flow?
For example if I open an IO Stream in the flow {} builder, how do I clean it up? I can't use onCompletion, because I don't have the stream available there obviously. If I understand the docs correctly I am not supposed to use try-finally in the flow {} builder, correct?
