Dunno if it's worth it, but maybe DCHECK that child_process_id is 0 for now, and
later DCHECK that it's NOT 0 so we know we're passing it around correctly
everywhere? (Tests could be -1.) - Again, dunno if it's worth it.

I'm not sure a 0-check really buys us anything.
The later DCHECK makes sense to me though.
