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?
