Most functions in this file are not used and slated to be removed. Are you
actually hitting this codepath?

we hit this codepatch in this CL. We need to check for parental control on
IOThread, and the existing method IsParentalControlActivityLoggingOn "should
ideally be called on the UI thread", thus i added a cached version safe to
access from any thread. However after second thought, i think it is better to
cache the value in ProfileIOData and keep this file unchanged. Please see patch
3.
