You can also send a space every second or so, and thus giving the client
the feel of a _really_ slow connection (it won't disconnect at all then).
When you have your result, you spool the whole lot.. You could maybe also
use dots, so that the user sees some progress.. You would have to
experiment there, though, since the browser might not show you the dots
because it feels that it need more information before rendering. Top of my
head here: it won't work inside a half-made table, maybe not with <center>
or stuff like that..
