* Note that readpartial behaves similar to sysread.
* The differences are:
* * If the buffer is not empty, read from the buffer instead of "sysread for buffered IO (IOError)".
* * It doesn't cause Errno::EAGAIN and Errno::EINTR. When readpartial meets EAGAIN and EINTR by read system call, readpartial retry the system call.
* * It doesn't cause Errno::EWOULDBLOCK and Errno::EINTR. When readpartial meets EWOULDBLOCK and EINTR by read system call, readpartial retry the system call.
*
* The later means that readpartial is nonblocking-flag insensitive.
* It blocks on the situation IO#sysread causes Errno::EAGAIN as if the fd is blocking mode.
* It blocks on the situation IO#sysread causes Errno::EWOULDBLOCK as if the fd is blocking mode.
