Wow… this is an excellent article. I’ve always been fascinated by GCs (well, as long as I’ve known what they are), and I just love seeing this kind of technical but accessible explanation of how they work, their bottlenecks, and a great new idea about solving those bottlenecks. This is exactly the kind of article that I hope to see every time I load up hacker news

Appreciated the human element paragraph at the end!
