As noted while debugging <https://issues.guix.gnu.org/59784>, turning
off networking while =E2=80=98guix substitute=E2=80=99 is downloading (be i=
t with
=E2=80=9Cifconfig X down=E2=80=9D or by physically unplugging the cable) le=
ads it to be
stuck in =E2=80=98read=E2=80=99 or =E2=80=98recvfrom=E2=80=99 for a long ti=
me.

Most likely this can be addressed by setting SO_RCVTIMEO and SO_SNDTIMEO
to a reasonable value on the socket.
