perftest and topictest are crashing and/or hanging on trunk, my fault, I'm working on it.
Related question: perftest & topictest are very similar. I'd like to merge them into one, based on the perftest single-program model. If there are features of topictest that aren't currently in perftest, let me know so I don't drop anything important. The only one I can think of is some extra configurability, which I will port over to perftest. Cheers, Alan.
