nit: as you use unique_ptr on 29, use unique_ptr here too. Also, include
#include <utility>.

[mfomitchev, 2016/04/08 15:47:40]

Oops, replaced with unique_ptr, thanks.
unique_ptr is defined in <memory> though, I don't think we need to include
<utility>.
http://en.cppreference.com/w/cpp/memory/unique_ptr
If you are looking at the chromium-dev PSA, it listed <utility> in error (which
was later corrected).

Indeed. I got the <utility> include from an early email from Daniel, I didn't
see the cc's that said use memory. Sorry.
