# The whole OS. Probably it just reflects on how unpredictably W98 can

Correct guess. 

NT also goes into an infinite loop, which can be seen by looking at the 
task manager's CPU % display. However, under both the Command Prompt 
window and the Cygwin B20 window (aka bash), ^C also stops working, unlike 
when you do a deliberate infinite loop:

    ruby -e "loop { puts 'Still busy!' }"

Interesting multiple ambiguity....
