You probably want base::test::ScopedCommandLine instead. This modifies a global
shared by all tests in a single process. I think this only works because this is
part of cast_base_unittests, which is tiny. If you did this in chrome's
unit_tests, it would have screwed up the global state badly for other tests
running as part of the same process.

Thanks, filed crbug.com/628219.
