+100.
(note, thats purely selfish. The more questions others ask the
experts, the more I learn.  ;)

On the last lecture students learned about the basic ideas of garbage collection which was exemplified on Pharo/Squeak. However I found the slides a bit outdated as they explained mark and sweep as well as basic tenuring. To my knowledge Spur is more complicated as it has the scavenger garbage collector, has multiple generations of objects, etc. Is there any presentation of a paper describing how GC works in Spur? Because some students want to learn more (as well as myself).
