+  //
+  // An update to the database has the following steps:
+  //
+  // 1) The update process is started with beginUpdate().  The client
+  //    passes an nsIUrlClassifierUpdateObserver object which will be
+  //    notified as the update is processed by the dbservice.
+  // 2) The client sends an initial update stream to the dbservice,
+  //    using beginStream/updateStream/finishStream.
+  // 3) While reading this initial update stream, the dbservice may
+  //    request additional streams from the client as requested by the
+  //    update stream.
+  // 4) For each additional update stream, the client feeds the
+  //    contents to the dbservice using beginStream/updateStream/endStream.
+  // 5) Once all streams have been processed, the client calls
+  //    finishUpdate.  When the dbservice has finished processing
+  //    all streams, it will notify the observer that the update process
+  //    is complete.
