I must admit I did not examine all of the code very closely -- and it's 
probably not gonna be productive to be picking code nits in such a huge patch. 

I have a couple of higher-level comments:

1. From the *MI* docs it is not apparent why the 'visualizer' passed is called 
with varobj to get the real visualizer. Docs probably should be more explicit.

2. I am unsure about the -var-set-child-range function -- why is this an 
integral part of this patch? Was this tried with any frontend, and found 
sufficient/good? I don't think we ever reached a conclusion as to how to deal 
with big number of children.
