As I said, I'm not blaming anybody. Any workflow which requires
force-pushing on a regular basis is broken. In particular, I wouldn't
want to encourage contributors to make their own scripts.

To that end I'm suggesting an official "Isabelle tool" which schedules
testboard builds. Ideally this would push to some fresh repository,
schedule a build, and delete the repository again. Users would write
"isabelle testboard" and be done with it. I'll sit down on the weekend
and try to come up with a proof of concept.

Cheers
