Really it must be called before any of the other functions correct?

If so, update the comment and change all the function guards to be
DCHECK(initialized_) rather than checking for specific variables (eg
extension_info_map_).

[pauljensen, 2012/12/14 16:16:20]

Well any of the Get*() methods other than GetResourceContext() or
GetMetricsEnabledStateOnIOThread().  I've updated the comment and DCHECKs.
