www.php.net/flush may help you out, but there are many reasons for
even that not to work... such as IE needing at least 256 (out the top of
my head) bytes before showing anything, IE needing all data in a
<TABLE> before showing it and commonly to make sure you send at least some
20 characters or so before being able to flush() again.
