Refinement #1.

unwind dummy frame id (next_frame)

Given the `next' frame, use frame_register_unwind() to construct the 
dummy frame's ID.

Why?  Because this also needs to work when the dummy-frame isn't 
innermost (the inner most frame edge case is covered by passing it the 
sentinel frame).

(my brain hurts!)
