#
# read_nonblock causes EOFError on EOF.
#
# On some platforms, such as Windows, non-blocking mode is not supported
# on IO objects other than sockets. In such cases, Errno::EBADF will
# be raised.
#
# If the read byte buffer is not empty,
# read_nonblock reads from the buffer like readpartial.
# In this case, the read(2) system call is not called.
