"use strict"; ?

Done.

Did you test that? Not sure if it'll work as the working dir for benchmark
execution is the same as the json file of the benchmark or relatively deeper (as
specified in the file).

We can also fix that later when landing the benchmark stuff.

[Michael Achenbach, 2015/05/19 09:34:47]

Just ignore this. I was confused. I assume when running the benchmarks with the
run_perf we don't use this file at all...

[bradn, 2015/05/19 09:37:53]

So the benchmarks or these tests run ok if you change the cwd to where the test
is.
This also works to run both, though the benchmarks are slow.
