A backtrace after "select-frame view" will still start at the
current (machine register's) frame.  Maybe it's sufficient to emulate it with
a sequence of "up" + "frame", though.  Keep in mind that you'll lose the view
with "info threads" or any command that flushes the frame cache internally,
as I mentioned in that ancient discussion.
