In addition to the request queue and the dirty queue, there are now also a requestPrio and requestBulk queue. The rendering order now is first render requests from requestPrio, then from request followed by the dirty queue and finally if no other requests are queued, render from the requestBulk queue. RequestPrio, Request and RequestBulk all block, whereas Diry immediately returns with NotDoneYet. This also changes mod_tile to submit requests that if not rendered in time would result in 404 errors as high priority. prioBulk should be useful for things like rerendering all the outdated tiles in the background, but this patch does not include those changes.
