        // statement right before the last one (the return), everything is
        // returned correctly and there is no seg fault.
        //
        // I'm always very leery to call something a compiler bug.  However,

//    Disable the section of code which allows re-using of entire networks.
//    This allows us to continue caching networks, but avoids the temporary
//    problem where different networks' plots might use different values
//    but we have not checked to see if the plots are equivalent.
//    Also....  I changed the way the networks are hooked up to allow for
//    zero-length pipelines.
