When I tested si:file-stream-fd the intention was to verify if it works
so that I could possibly implement an alternative function which
instead of using fileno(3) on the file handle could possibly report the
fh error/eof state.  Because unfortunately, FORCE-OUTPUT will not
report at all why it stopped flushing if an error occurred, so I should
either be able to use fflush(3) from C and/or ferror(3)/feof(3), but
for that I need the pointer to the underlaying stdio FILE stream.
