 // the IO thread, such as, but not limited to, network objects like
 // CookieMonster, HttpTransactionFactory, etc. OffTheRecordProfileIOData is
 // owned by the OffTheRecordProfile and OffTheRecordProfileIOData's
 // ChromeURLRequestContexts. When all of them go away, then ProfileIOData will
 // be deleted. Note that the OffTheRecordProfileIOData will typically outlive
 // the Profile it is "owned" by, so it's important for OffTheRecordProfileIOData
 // not to hold any references to the Profile beyond what's used by LazyParams
 // (which should be deleted after lazy initialization).
