Same question here: Why is this flag needed? Is this something devs would want
to set when running the test too? If so, should ti just be on by default?

[Daniele Castagna, 2015/03/02 22:45:19]

My hypothesis is that with this flag we make sure perf_test::PrintResult writes
directly to stdout. The infrastructure we have for perf tests reads directly
from the output of the tests. This is what I'm guessing given the last comment
of crrev.com/963203002. If someone from the Chrome Speed Team wants to clarify,
I'd be happy to hear that.

I tried to run the test locally and I see the perf results on stdout without
that flag.
