 // One of these objects will be created by WebKit for each request. WebKit
 // will own the pointer to the bridge, and will delete it when the request is
 // no longer needed.
 //
 // In turn, the bridge's owner on the WebKit end will implement the
 // RequestPeer interface, which we will use to communicate notifications
 // back.
