I hadn't yet tried profiling the programme. I actually deleted it a few days ago. I'm going to try to get something new running, and I will report back. On a slightly less related track: Is there any way to use cassava so that I can have pure state and also yield CSV lines while my computation is running instead of everything at the end as would be with the State monad?
