c.ask() / c.retry(), or a wait started from a c.idle() callback. A
conversation has a single pending-wait slot, so the newer wait is refused (the pending one
keeps receiving messages). Not a control signal: in the conversation it ends through the
error path (onError / bot 'error' event + errorMessage); in an idle callback it is only
reported.
