I was about to write off this benchmark while working on GVL
improvements on multi-core systems.
However I noticed it exposes a weakness in my work-in-progress
code when I tested on an old single CPU system. Further testing
reveals setting CPU affinity ("schedtool -a 0x1" on Linux) on a
modern multi-core system is enough to reproduce the problem
exposed by this benchmark.

# n.b. this is a good test for GVL when pinned to a single CPU
