Depending on how deep the call stack is and how frequently we push and pop
stack frames, being able to not unwind some number of frames can be a
significant savings.

Isn't this assuming that the stack frames are unique? How would you handle
recursion under this scheme?

I do not understand the question.  Recursive calls get new stack frames.  Stack 
frames from recursive calls and stack frames from non-recursive calls are 
handled identically.

Nevermind, I think your solution is talking about function addresses, not stack frames.
