 // This is a bit confusing. The "old-style" resources live in
 // webkit/plugins/ppapi and are created by the ResourceCreationImpl in that
 // directory. The "new-style" IPC-only resources are in ppapi/proxy and are
 // created by the RessourceCreationProxy in that directory.
 //
-// This class allows us to run new-style IPC-only resources in-process. We have
-// an IPC reflector to run it in process. But then we have a problem with
-// allocating the resources since src/webkit can't depend on IPC or see our IPC
-// backend in content. This class overrides the normal in-process resource
-// creation and adds in the resources that we implement in ppapi/proxy.
