+// This class is the IPC half of the glue between the
+// nsIWebBrowserPersistDocument interface and a remote document.  When
+// (and if) it receives the Attributes message it constructs an
+// WebBrowserPersistRemoteDocument and releases it into the XPCOM
+// universe; otherwise, it invokes the document receiver's error
+// callback.
+//
+// This object's lifetime is the normal IPC lifetime; on destruction,
+// it calls its XPCOM reflection (if it exists yet) to remove that
+// reference.  Normal deletion occurs when the XPCOM object is being
+// destroyed or after an InitFailure is received and handled.
+//
