I was talking with Patrick Dussud, the Architect for the CLR's Garbage Collector today and it turns out he has a very good presentation that he does for internal groups that need to understand the philology behind how the GC really works.  This is one of those “more than you really every needed to know” kind of things. 

Of course my first through was getting that information to you folks as I am sure you are interested.  Patrick was gracious enough to let me posted it.. Enjoy!  And I do realize that plagiarizium is the highest forum of flattery, but I would like to know if you find this stuff valuable and if so why.
