Im sorry for my ignorance, but I dont understand how HN can have memory leaks. I learned Scheme in school and from what I remember memory is handled automatically (in the particular one we were studying I think it was via reference counting). Is Arc that different from Scheme or am I just completely unaware of how Lisp works behind the scenes?
Garbage collection is cruise control for memory management, but you still have to steer. The only thing GC gives you is automated cleanup of orphaned data; if you're sloppy about holding references you don't need anymore, the GC won't help you.
