Oh, we need a meta-GC now :)

Seriously, I think we have to make some restrictions on Lisp
programs so they don't keep Scheme values.  I think people of
Guile Emacs do not want to write new programs in Lisp, so it's
not a problem.  If people of Lisp want to use Guile's features,
it is the time to move to the Guile-based Emacs.
