Motivation: Before we used a long[] to store the ready events, this had a few problems and limitations: - An extra loop was needed to translate between epoll_event and our long - JNI may need to do extra memory copy if the JVM not supports pinning - More branches Modifications: - Introduce a EpollEventArray which allows to directly write in a struct epoll_event* and pass it to epoll_wait. Result: Better speed when using native transport, as shown in the benchmark.
