Which operating system and terminal did you use?

In my experience, using print is not satisfactory, because the print 
command buffers the output and doesn't actually print anything until 
either a newline or you have a certain number of characters. So the 
above will queue up the following string:

"10 \r9 \r8 \r7 \r6 \r5 \r4 \r3 \r2 \r1 \r\n"

before anything becomes visible, and of course that just looks like "1".
