    Ignore SIGPIPE signals to avoid process termination on cancelled transfer
    
    That way we would be able to properly get EPIPE when trying to write to
    a socket or pipe whose far end has been closed. This happens e.g. on
    file copy cancellation. Glib does similar thing on GSocket initialization.
