Lol, I did something like the
while (1) ;
in some coursework last year at University. Had to write a C program that demonstrated concurrency between multiple threads. The problem was a bathroom problem. The threads (people) would join a queue. These would be set to men and women. Women had priority and as many women at once could enter the bathroom, but only one male would enter at any one time, so the bathroom would fill up with women at some point, and I just put a semaphore block down and then put an inifite loop as a joke to say the men are gonna be waiting a while, lol.
