Motivation: 73dfd7c01b49aca006a34cc48197dee3fc360af1 introduced various test failures because: - EpollSocketChannel.doWrite() raised a NullPointerException when notifying the write progress. - ChannelOutboundBuffer.nioBuffers() did not expand the internal array when the pending entries contained more than 1024 buffers, dropping the remainder. Modifications: - Fix the NPE in EpollSocketChannel by removing an unnecessary progress update - Expand the thread-local buffer array if there is not enough room, which was the original behavior dropped by the offending commit Result: Regression is gone.
