More info about in-memory support in Java DB

Knut Anders gives lots of useful details about the new in-memory support in Java DB 10.5. Very simple to use: just specify "memory" in the URL. I love the tip about backing up your in-memory database prior to exiting the application - it's like doing one big checkpoint at the end. So you get both durability (OK, very large-grained durability :)) and speed.
