Instead of outputting to the browser, couldn't the CGI write a .shtml file, and send an HTTP "Location:" header to the browser that redirects to the outputted file? The downside is that you'ld have to have it write unique files each time it's accessed to prevent conflicts if one person hits the script before another has finished downloading the output (Maybe a filename based on the time?). You'ld also have to have some way of flushing out the .shtml files every so often. (Maybe this isn't such a great idea.)
