You can zap them by Unprotect[Out]; Clear[Out]; Protect[Out]; or use CleanSlate package by Todd Gayley found on MathSource. Mma 2.x does have some memory leaks though. In my experience, the best thing to do is simply quit and restart. You can just quit the kernel by the command Quit. In mma 3.0, you can use $HistoryLength=5; to specify number of previous results to be saved. Xah, xah at best.com, http://www.best.com/~xah/ "Mathematics kills germs, cleans the toilet too."
