Does this really belong in GDB? I ask because we've resisted adding
similar things for other targets before - at least I have for Linux
and for Xfree86, but maybe I should have been more accepting.
Anyway, I have some thoughts on how to extend the unwind mechanism so
that the OpenBSD kernel could ship a script that knew how to unwind its
trap frames. I'll be posting about that at the beginning of 2007, just
as soon as I clear my review backlog and the pointers-to-members patch,
I hope!
