It happens because ultimately you produce a bind expression such as

    boost::bind( pImpl, this, ..., boost::ref( value ) )

and the ref is interpreted by bind as a reference to 'value'. But your Arg1 
remains a reference_wrapper. You'll probably need to convert ArgN parameters 
that are of the form reference_wrapper<X> to X& before instantiating 
create_processor_implN.
