The SIGTERM comes from my less-than-ideal way of spinning up marionettes
outside of the derivation that carries out the srfi-64 tests,
'call-with-marionette'. I have a line with '(kill pid SIGTERM)' as the
QEMU guest will otherwise continue to run after the test suite exits. I
commented out the line and verified that after the error occurs, the
guest is still running (and accessible via SSH).

What's interesting is, if I leave the guest running, SSH in, set up
public key auth and run 'guix deploy' from my shell, I don't get the
socket error.

Very unusal. I'm wondering if it's caused by my use of
'call-with-connected-session/auth' from (gnu tests ssh) rather than
'open-ssh-session' in (guix ssh). That's the main difference between the
test suite and 'guix deploy' in terms of how they communicate with the
guest.
