 // Initial sync setup:
 //
 //   For privacy reasons, it is usually desirable to avoid syncing any data
 //   types until the user has finished setting up sync. There are two APIs
 //   that control the initial sync download:
 //
 //    * SetFirstSetupComplete()
-//    * SetSetupInProgress()
+//    * GetSetupInProgressHandle()
 //
 //   SetFirstSetupComplete() should be called once the user has finished setting
-//   up sync at least once on their account. SetSetupInProgress(true) should be
-//   called while the user is actively configuring their account, and then
-//   SetSetupInProgress(false) should be called when configuration is complete.
-//   Once both these conditions have been met, CanConfigureDataTypes() will
-//   return true and datatype configuration can begin.
+//   up sync at least once on their account. GetSetupInProgressHandle() should
+//   be called while the user is actively configuring their account. The handle

+//
+//   Once first setup has completed and there are no outstanding
+//   setup-in-progress handles, CanConfigureDataTypes() will return true and
