 // permanently store the data used to make predictions, and keeps local caches
 // of that data to be able to make predictions synchronously on the UI thread
 // where it lives. It can be accessed as a weak pointer so that it can safely
 // use PostTaskAndReply without fear of crashes if it is destroyed before the
 // reply triggers. This is necessary during initialization.
