Then there is a big problem on your machine. To stress-test crafty, I play games with the time control 999 moves in 1 minute. The games go to 100-200 moves with _no_ time problem at all. I notice you said one machine. That's not a reasonable test. Make one program's hash too big and that ends it... paging a program in and out is not going to work... But I'll be happy to let you play either of mine on ICC (Crafty or Scrappy) for any time control you want to convince you that it will _never_ lose on time.
