Added quite a few more classes here, for consistency with bootstrap.js in
buildtools.

 
   let shutdownHandlers = [];
   let onShutdown =
   {
     done: false,
     add: function(handler)
     {
       if (shutdownHandlers.indexOf(handler) < 0)
         shutdownHandlers.push(handler);
     },
     remove: function(handler)
     {
       let index = shutdownHandlers.indexOf(handler);
       if (index >= 0)
         shutdownHandlers.splice(index, 1);
     }
   };
 
-  let callbackPrefix = Services.appinfo.processID + " ";
-  let maxCallbackID = 0;
-  let callbacks = new Map();
+  function init()
+  {
+    let url = new URL(Components.stack.filename);
+    let params = new URLSearchParams(url.search.substr(1));
+    let info = JSON.parse(params.get("info"));
 
-  function sendSyncMessageSingleResponse(messageName, data)
-  {
