Comment (by stefan):
Originally, we were running this instance from GAMS with a timelimit of
3600s.
With GAMS/Cbc, I can also enable the log from Clp.
It shows that after the {{{Postprocessing changed objective}}} line, a lot
of LP solves happen again, I even see some output about strong branching.
