Well, I don't know but there may some strange behavior related to how Ubuntu handles sleep? If you put your Perl program into an tight loop, or have it do an blocking IO operation or have it read a big disk file line by line, I betcha CTL-Z will do something. Is this a real application question or just intellectual curiosity? Perl itself is not going to do anything with CTL-Z without a lot more code than 2 lines!
