bulk loading documents

Is it possible to bulk load documents without having to load each document individually? It seems very wasteful to have to do so many roundtrips to the db for each document, yet alone for many documents. My xwiki schema/hibernate knowledge isn't that good, so maybe there is no alternative, but I'm just wondering if someone has thought about it and come up with a way to load multiple xwikidocs (or even all of a single xwiki doc with its classes/properties/ attachments/etc) in a single query.
