Summary: this is a useful idea, and v2 fixes the concrete v1
problems.  Before v3, I'd like to see the "does this belong in
GDB" question settled with the maintainers.  On the code side, I'd
most like to see M1 (PID namespace), M2 (partial debuginfo), M3
(unhandled drgn exceptions) and the drgn.internal / sys.executable
dependency (M4) fixed.


Hi Kevin,

thank you very much for the insightful review. I'd love to get more feedback 
on  "does this belong in GDB" question. 

Thank you all,
Alexandra
