The "by default" makes it sound as if there is a way to force
'post-commit' alone serially, but other than hook.jobs that can be
used to uniformly make everything run serially, I didn't find a way

Yeah, hook.jobs is the way to make it run serially, and as you say, it
can't be applied everywhere. I'll try to change the language.

The comment applies to all the "by default" in this latter half of
the series.

Thanks.
