* Note that readpartial behaves similar to sysread.
* The differences are:
* * If the byte buffer is not empty, read from the byte buffer instead of "sysread for buffered IO (IOError)".
* * It doesn't cause Errno::EWOULDBLOCK and Errno::EINTR. When readpartial meets EWOULDBLOCK and EINTR by read system call, readpartial retry the system call.
