Its not supposed to break anything, but I doubt it has ever been tested. Something that might be interesting is to compile a kernel with the counter pre-initialized so that it will overflow in about 5 minutes. Then some network connections, compilers, etc. could be started up, and we could see what happened when it overflowed.
Something that would probably be a very good thing to do is during the 2.1 development cycle, change the kernel so that jiffies *always* overflows after 5 minutes. It would be a very good way of making sure that we can always handle the overflows correctly, and it's also a good way to keep future device driver developers on the straight and narrow.
