optional nit (since it is in the original CL), ScopedVector is deprecated.
https://code.google.com/p/chromium/codesearch#chromium/src/base/memory/scoped...

Might consider using std::vector instead.

[pauljensen, 2015/12/02 03:50:02]

Let's leave that for another CL, especially because I find
ScopedVector<QuicHint> more readable than std::vector<scoped_ptr<QuicHint>>.
