// This class is the XPCOM half of the glue between the
// nsIWebBrowserPersistDocument interface and a remote document; it is
// created by WebBrowserPersistDocumentParent when (and if) it
// receives the information needed to populate the interface's
// properties.
//
// This object has a normal refcounted lifetime.  The corresponding
// IPC actor holds a weak reference to this class; when the last
// strong reference is released, it sends an IPC delete message and
// thereby removes that reference.
