catchUp held the teller's lock across the router's record read (Where, through operatorask.Bucket and seatlist.HolderOf,
which retries); with no answer it blocked the module's event pull, whose Said waits on that lock (met when an ask arrived
inside a first view). OnAssignerAsk now catches up after it let go of the lock, catchUp takes the lock only once the record
is read (an asking no longer open by then is left), and OnCurrent reads the records of the asks asked again outside the
lock in the same way.
Builds: design 47 G §717 (the teller raises the assigner's asks whether or not anything else answers, issue 1906); principle 3
