Amen.  One comment, regarding the sequence trace:


On the left hand side, at Obj5 return-> Obj2:  visually I was  
expecting a return arrow pointing left (<-return), but the order Obj5  
-> Obj2 makes sense, and Obj2 <- Obj5 might be confusing when looking  
down columns 1 and 3 (column 2 being the arrows/messages).  Maybe the  
word return above the arrow could be slanted.

The arrows on the right hand (wide) part of the sequence diagram are  
completely clear.  The sequence diagram is the clearest I've seen.  I  
have some fancy expensive Java tools that don't even come close.

Thinking about Java made me think about threads, which of course PLT  
Scheme has too.  I wonder what these diagrams would look like with
