My usual workload (building new Linux kernels - what else :-) doesn't seem to generate any unwind requests. I reached the loop just 58 times while booting, and only did 23 steps past the first item [didn't track a histogram, so I don't know whether that was a single 23 step lookup, or 23 one-step ones]. Building the kernel (make -j32) didn't add to either count.
Workload ideas?
