I know, but I'm talking about sessions that run for 6h. If they take 8h, I'd like to be able to see roughly where they are stuck, preferably on the same day, so I can skip proofs to that point and investigate. Even with concurrency I can usually figure out which set of theories is currently running (and some big sessions run with -p 1 anyway to reduce memory usage).
