Maybe it is just a coincidence, it did work for Isabelle/18cb541a975f
vs. AFP/9181c1974aa0, but later failed again for AFP/e064b4022c1c -- see
also the "CSV" link on https://isabelle.sketis.net/devel/build_status

Later today we should get new measurements.

This is indeed a bit fragile. I used to make manual tests of
Flyspeck-Tame over some time, but now ignore that problem.

Several days of unclear situation is a natural consequence of this
arrangement.

Maybe it is possible to make a non-slow session "Flyspeck-Tame-Base"
that does everything except the actual "eval" steps, and postpone the
checks to session Flyspeck-Tame (very_slow) = Flyspeck-Tame-Base ...
