it gobbles memory up quickly and forces a 4gb mac mini under 10.7.2 into swapping almost instantly all the way up to a 4gb swapfile. It's fun to use, but at the pain of having to do reboots. Having it launch at boot makes this happen. Once you're booted you can run the app, but it has a leak somewhere which I don't have time to track down. Wish someone else would and report it back. With it running I am at 4gb of swap in moments. Without it, 256mb of swap for more than 10 hours.
