Have a look at memcached.

Why?

I don't know what it means to "repaint" the screen. That sounds like
something which is entirely the web browser's concern, so I'd probably
avoid sticking my nose into it.

Why would they be reloading the page if they wanted to have the same
several thousand items after the reload as before? Maybe you can use
frames to separate the things that change upon reloading from those that
don't.
