I got about 4-4.5% CPU usage and around 100MB memory usage. It never locked up on me, though, although I didn't run into any dragons. I guess I have more exploring to do. Looks good so far, but if there's a bug I didn't hit it.
EDIT: I've been in three caves and fought a dragon in each with no issues other than I have no way of knowing if I actually slew them. It just pops me back outside. It might be an issue with your computer, mine never locked up. Scratch that, on another go I locked up just as I was fighting a dragon. I think it was after the beeps that indicate victory.
