You will need to run your loopy method in a separate thread, and then  
kill that thread when the user presses any key on the keyboard ...

t = Thread.new do
   i = 0
   while true
     i += 1
     puts i
   end
end

gets
t.kill

The above code won't work with any keypress -- you have to hit enter  
in order to stop the program.
