I've been wanting to run valgrind on chunkd, but each time I attempt it, I -- and valgrind -- have been overwhelmed by openssl false positives. openssl, deep in its RAND_xxx functions, intentionally does crazy stuff like using random, uninitialized stack contents as RNG entropy. Cute, but valgrind quite rightly complains loudly about it. It's a topic I've been meaning to research, because I currently lack the valgrind-fu necessary to have an effective valgrind+chunkd session. Thanks, Jeff
