I agree with Alexander. If it were really a frame you'd have to expose
a frame constructor to Python/GDB, and then would the resulting frame be
interned? What would happen if you built a frame but then returned
None, or threw an exception? Would there be side effects to the frame
cache? And if not, could you hold on to the frame? Would it be equal
to frame.newer().older() ? Better to return data instead, which GDB
uses to build the actual frame.
