I mean to say the biggest problem I see is the cross-win64-system
job. This consumes 1 hour 5 minutes all on its own. It is at least
15 minutes longer that every other job AFAICT. So no matter how
well we parallelize stuff, 1 hr 5 is a hard lower limit on pipeline
duration right now.

We might want to consider how to split the win64 job or cut down
what it does in some way ?
