After more playing with it, the high latency under mod_deflate is caused
by the change required to make 'flush' work (setting a low SetOutputBuffer).

I'm _trying_ to make the javascript start being loaded while the CGI
finishes putting together the page. It seems I can have one or the other
(working flush, or fast mod_deflate).
