I think we can always allocate xnull before checking for the config.silent property and redirect only if this is needed. That would avoid a dynamic allocation here. Also we could take the opportunity of fixing this issue to write a small RAII object to perform the redirection.

std::cout.rdbuf(nullbuf.get());
std::cerr.rdbuf(nullbuf.get());
}

std::string err;
