As I recall there wasn't much discussion, unfortunately. I very vaguely 
recall that there was some worry that Emacs modules would be written in 
C++, and that they would invoke Elisp code, and that this meant it'd be 
hard to do the cleanup in portable C.

One option that was discussed was to require a C++ compiler to compile 
emacs-modules.cc (i.e., to write the emacs-modules interface in C++). I 
expect this would have addressed the cleanup issue in a different way. 
But RMS was very strongly against requiring a C++ compiler.
