 // binding proxies to remote interfaces, but this is specifically for interfaces
 // which must be assocaited with an IPC::Channel, i.e. retain FIFO message
 // ordering with respect to legacy IPC messages.

 // The Channel with which the remote interfaces are associated depends on
 // the configuration of the specific AssociatedInterfaceProvider instance. For
 // example, RenderFrameHost exposes an instance of this class for which all
 // interfaces are associted with the IPC::ChannelProxy to the render process
 // which hosts its corresponding RenderFrame.
