I think the example could be improved a bit. We have

def process_commands(*args):
    while True:
        line = ''
        while not line.endswith('\n'):
            line += read_next_char()
        if line == 'quit\n':
            print "are you sure?"
            if read_next_char() != 'y':
                continue    # ignore the command
        process_command(line)

but the *args are ignored and 'process_command' looks too similar
to process_commands; also the continue line looks strange.
Why not just

def show_entered_commands():
    while True:
        line = ''
        while not line.endswith('\n'):
            line += read_next_char()
        print line
        if line == 'quit\n':
            print "are you sure?"
            if read_next_char() == 'y':
                break

? Anyway, this is a pretty cool example of what you can do with greenlets.
