A great introduction to garbage collectors: Storage Management, cont'd (MP4 file) (Paul Hilfinger). It was fun to figure out how to implement this. Just a short link, I didn't want this to get lost in my twitter stream. :-)

Lessons learned: My first C program with a void***. Should have used more unions. Just about 200 lines of C, a working stop-and-copy garbage collector. :-) A fun hack, but hard to test. It's probably buggy. ;-)
