The problem is the fact that you're writing to a file on the fly - but it's
server-side.  You may write the header to the temporary file in the
application using wrtsection('top'), but the server isn't going to send any
data over to the browser until it's ready for the full request.

Your best bet, if you really need to have something up on the screen right
away, is to break it up either into two frames (top frame is static and
loads immediately, while the bottom frame is processing server-side), or
present a "Results Loading" page that redirects to the data page once
processing is finished.  You should be able to do that right in your CGI.

Hope that helps!
