One of the "one"s seems redundant.

Jan> +    CORE_ADDR morestack_start, morestack_end;

Is it impossible for __morestack to appear in multiple objfiles?  What
if you have a program that dlmopen()s two versions of the shared library
defining it?  I don't know how strict we want to be about this kind of
thing -- we don't actually support dlmopen in any meaningful way right
now anyway.

I think this would also need to hook into objfile_relocate.

A new frame type seems like an ok idea.

I don't mind this approach, though I'm also interested to hear what
others think.
