sleep not adding up

[Jeff Bowen]

I was hoping that the following code would print out hi with one second
gaps. However it waits 5 seconds and then prints out hi 5 times.


def test_puts
puts 'hi'
end

def test_sleep
sleep 1
test_puts
end

5.downto(1) do
test_sleep
end

It works as you expected on my box (Linux). What's your platform?

On windows, you need to manually flush STDOUT/STDERR if you want to see
the output prior to the program ending.

Yes - or read some input from $stdin. A difference in the C library
settings which might depend on which type of build you're using.
