There is another problem. If I use FileOutputStream, the message would not be flush whether Flush() is be used or not. It would be flush until the file descriptor is closed.
It is still the EOF's problem? if yes, it looks not suitable for socket programing. I have seem the same problem on SerializeToFileDescriptor.
