Send a series of lines with the same info over an input channel, as was 
done 3 years later for FastCGI. Since CGI uses stdout for the finished 
product, it could have used stdin for the input. Using a serial channel 
does put more burden on the page server to parse the input. But is 
allows it to be on a different machine.
