No problem.  Just glad I could help in some small way.

I hadn't had time to really test it.  I just ran 'generate-core-file'
from
GDB today though and did manage to create a core using your code, so the
'find_memory_regions' seems to work ok.  In order to get it to generate
a core file, though, you need to fill in a notes section by giving GDB
a notes section hook:

  gnu_ops.to_make_corefile_notes = gnu_to_make_corefile_notes;

I dummied up one for now and thought I would wait for your thinking on
notes formats to solidify before adding "real" code there, but whatever
note format is used in 'crash' should also go here.

D'oh.

Let me know if there are any other ways in which I can help on the
project.
