No, one "RunUnit" per process

I was sloppy, not knowing where the questions were going. The AI and BI journalling record buckets (up to the free byte mark).
RU journalling is record based and impacted Records stay locked for the duration of the transaction.
The picture in the Journaling manual under "5.2.4 Transaction states" may be helpful there.
