True, that's also why I picked that one. It's the only one I knew of that's both in a modern language, relatively small (just under 10k lines at that time) and that had serious production grade performance. It was a bit controversial because they apparently determined that adding the advanced optimizations of modern GC's would negatively impact GC times, so the GC was intentionally kept very simple. I don't know if they maintained that attitude since then.
