Found after the last commit: a message being passed on toward a node that
was stuck held the node passing it on in the wait, taking in what came
but serving none of it; text typed for a stuck node left Hera deaf. And
a node that had done text for a sender that then stuck waited on it to
give its answer.
A node with nothing to do now deals first with what is for itself; then
offers at once the first message for each port and each refusal owed,
and sleeps in the wait. What is taken is written and done with; the
rest stays with the messages waiting, in order. How text ended is put
with the messages waiting, not written from (FINISH). The stack is kept
as shallow between lines as it was.
