maybe call this 'stored_version_size' (or even just stored_size for greater
brevity) since it can be either the active or waiting version depending on where
things are in the update algo

also i think int64_t might be a better type since its the sum of multiple file
sizes

Done.

   ~ServiceWorkerRegistrationInfo();
 
   GURL pattern;
   int64 registration_id;
   ServiceWorkerVersionInfo controlling_version;
   ServiceWorkerVersionInfo active_version;
   ServiceWorkerVersionInfo waiting_version;
   ServiceWorkerVersionInfo installing_version;
+
+  size_t active_version_total_size_bytes;
 };
