Darkwing's row 59 review (comment 27487) found that a message delivered
to a run that releases the role unread can't be received or read by the
next holder. Sage's ruling: keep at-most-once delivery, as the bus
README promises, and list stranded messages in the agents read so a
person decides whether to resend. Owner Darkwing after row 59, reviewer
Filbert, held behind the cutover with the other bus rows (decision 94).
