[self-interest] Blocks: Summary

[David Ungar]

Thanks, Jecel, for explaining this stuff.
If there are new bugs in the latest release (looking at method 
objects or whatever)
please feel free to look at them and send me fixes, if you have time 
and if it would help you.
Dru, I'm curious. What are you working on that you need to know this stuff?

Thanks

- Dave
