I think it's libreadline that needs the file descriptors, actually,
FILE *s:

 - Variable: FILE * rl_instream
     The stdio stream from which Readline reads input.

 - Variable: FILE * rl_outstream
     The stdio stream to which Readline performs output.

The guile interface hooks up port file descriptors to these variables.
