Optimize circles a bit

After reviewing some disassembly elsewhere I realized that declaring a function
to return `(values)` and adding that form actually prevents last-call
optimization, at least in SBCL.  It's a cleaner API, but it wastes lots of stack
frames.

Save the frames, kill the `(values)`.
