I don't think "wrapper" is the right terminology here, I think "subclass" is the
correct term to use instead.

[SteveT, 2012/09/24 15:38:38]

Done.

Nit: Add an empty line within the comment here.

[SteveT, 2012/09/24 15:38:38]

Done.

Could this be simplified and merged with SetRequestsAllowed?

e.g. only have one method instead of two, and call it:

void SetRequestsAllowedOverride(bool allowed);

This would set |override_requests_allowed_| to true and |requests_allowed_| to
|allowed|.

[SteveT, 2012/09/24 15:38:38]

That simplified things a bit, yeah. Done.
