       *     Events from applications using alternative implementations of libc, making direct kernel

       * <p> Some common network events may not be reported. For example:
       *     <ul>
       *       <li>Applications may hardcode IP addresses to reduce the number of DNS lookups, or use
       *           an alternative system for name resolution, and so avoid calling
       *           {@code getaddrinfo()} or {@code gethostbyname}.</li>
       *       <li>Applications may use datagram sockets for performance reasons, for example
       *           for a game client. Calling {@code connect()} is unnecessary for this kind of
