Looks fine, but we currently have a evil hack in the generator


# only generate a close method if -c was passed
if ($opt_c) {
    # REMOTE_PROC_CLOSE has no args or ret.
    $calls{close} = {
        name => "close",
        ProcName => "Close",
        UC_NAME => "CLOSE",
        args => "void",
        ret => "void",
    };
}

it seems like your patch would let us remove this -c arg and the
corresponding code ?

Daniel
