Thanks for going into this. But https://isabelle.sketis.net/devel/build_status/ still indicates failure for Flyspec-Tame from Wed 13th. Is there any chance that some other non-termination proof requiring image_cong_simp [cong del] is still left in Flyspeck-Tame? Btw. that the ancient cond_eval hack has been replaced by a proper tag has completely slipped out of my attention, hence I didn't notice that Flyspeck-Tame is completely untested without very_slow. At the moment I am thinking whether the old approach of checking everything except the computations can be restored without using fancy low-level stuff. Maybe by a locale. Cheers, Florian
