There is nothing wrong with the code. Works for me as expected:

lua myscript.lua < /dev/null

io.read() by default reads whole line ('*l'). So you need to send it a
line (ending with CR/LF, or CTRL+D for empty line), or close the input.
Otherwise it waits in blocking read. You seem to expect it is
non-blocking. Try io.read(0) and read the manual:
