Sorry, I don't understand.  Do you mean to fix it "upstream" — i.e., in
guile?  If so, I agree as it sounds natural to me if guile will delete a
socket file it created.

Anyway, as I mentioned in the reply to Florian, I think the best would
be to add a procedure for deleting socket file to `kill-emacs-hook' (as
in the attached updated patch).  This should prevent appearing dead
sockets.

P.S.  Maybe it's a wrong impression, but it looks (to me) that
connecting to a socket is significantly faster than using a port (so all
this Guix REPL stuff starts faster).
