In contrast to my proposal concerning Flyspeck-Tame-Base it is better to
keep the main AFP document unchanged, e.g. like this:

  session Flyspeck-Tame-Eval (very_slow) = Flyspeck-Tame + ...

This will change the timing for Flyspeck-Tame in the recorded database,
but such renamings occasionally happen over the years.
