Comment on attachment 312466 [details] Patch Looks good to me. After this change, though, WebResourceLoadStatisticsStore::processStatisticsAndDataRecords is the one remaining lambda that captures [this], but does not ref/deref it. The one passed to coreStore().processStatistics. Perhaps that function is guaranteed to run synchronously?
