I posted patch based on apple-local-200502-branch for review on our  
internal list yesterday. How about reviewing that patch first before  
I port it to mainline ? If some one else, who does not have access to  
that list, wants to review it then it is a different thing, but this  
would save me some additional work.

It is not possible and very error prone. I tried to do it before I  
started this rewrite. When you see my patch, you'll understand.

I started using already modified Apple GDB, and Jim handled further  
modifications. You need to coordinate with him on this front.
