This shows an interesting strategy difference between the test_runner
and bench_runner.
In the test_runner we default to the least-stress configuration, to
minimize bugs unrelated to the current test. But the resulting
configuration is unrealistic, as most use cases on flash will probably
want wear-leveling.
In the bench_runner, we should use a more realistic configuration, so
setting BLOCK_RECYCLES=100 by default makes sense.
