Hello, I just spent a whole week tracking down and whacking memory leaks over the head, and I arrived on the other end of that week a little dazed. There has to be a better way to do this, is all I can think, and so I figured it was time to ask about this rather heavy subject. This post turned out to be rather huge. Apologies for that,...
