Seems that I picked a good moment for starting to ask around :-)

Good, so that's the way to go then.

You haven't seen the tiny little per-page trees hanging off
each requests yet ;-) I need them to "upgrade" requests when
someone with high priority decides to request a page that's
already in the queue. That should be a comparably rare event,
but handling that certainly adds complexity :-(
