- Any failure of a request the link may have delivered now says the line may have run; "nothing ran" is said only of a request the link knows it never asked (no link open, nobody listening: link.ErrNotAsked). - A test holds that a connection saying nothing is answered within its deadline, set at accept, and gives its slot back. - The README says the socket refuses a process outside the machine's own namespaces, so flatpak, toolbox and distrobox shells are refused.
