I'm not entirely sure about CGI but as it uses STDOUT underneath a 
use IO::Handle;
STDOUT->autoflush(1);

[download]
should at least get the HTML out to the web server. It won't solve the problem of the CGI script not exiting and thus not sending an EOF to the browser though, so the browser will keep showing "page loading". Maybe you can close STDOUT before exiting?
