oh, btw, I noticed that only ports are flushed on exit of GUILE (gc.c
- onexit ()). The manual talks about "freeing resources" for the smob
free function. I believe that is inaccurate: free is only for freeing
memory. Stuff like closing files should happen in an explicitly called
function, for the free() might never get called at then end.
