My gut feeling is that already today, I would prefer s/h to run
automatically on every intermediate proof state if this didn't
interfere with my editing. Why should the many cores in my machine sit
idle? It seems perfectly reasonable to spend a few billion CPU cycles
if that occasionally saves a minute or two of human time.

Architecturally, some kind of incremental mode for s/h (as suggested by
Jasmin) could reduce the performance overhead.
