In this case I didn't use run_branches.pl. I just opened up two sessions
and triggered two
separate runs for v16 / v17 (with --force) since master just came out
green. Efficiency aside,
at worst I was expecting two concurrent runs to be slower, but not error
out.

Unrelated, for a slow system my understanding was that it's quite
inefficient to keep running older
branches every few minutes (like HEAD does) - so for some of the animals I
explicitly run older
branches (for e.g. v13) every few hours, but HEAD runs every few minutes.

Are you saying it's still a good idea to run all together every few minutes
(and let older branches
skip if there's nothing to do)?
