Preload next article in background

[stiff]

When reading urls-only feeds (for example HackerNews) it takes some time to load next article to load. It'd be better if it was preloaded in background.

So for example, while I'm reading article A the next (the one which will be shown after deleting current) article B is preloaded, then I hit delete on A, B is shown immediately, C is preloading.

Or is it asking too much?
