A delivery record's pinned and freed reach the assigner on its durable
consumer, kept per revision in its old state pins by compare-and-set
before the event is acknowledged; a revision neither pinned nor current
is removed only while the consumer is caught up and after a pins-stated
said since the state was made, never on a timer and never by reading
the gate's state. assigner_pins reads it, assigner_unpin frees a lost
freed by hand, recorded in the hand-act log first.
