I haven't needed to use this yet, but I was considering what I would do
if I hit a problem like this just a few weeks ago. What I came up with
was some ajax feedback. During the exec of your script, you should
write to a file exactly what you would like to appear as feedback to
the user. You would then write some js to grab the contents of the
file that you have written to and display it on the page.

Haven't really tried it, but in theory its a sound idea as far as I can
tell.

As for timing out, im sure you've heard of set_time_limit()?

I'd like to read other people's ideas.
