We have shipping apps that open a power event notification at launch and then never close it with no problems. Have you tried to reproduce this on clean install of OS X? You can always open a bug with Apple, attach your sample code and see what they think. No matter how your app terminates, if you leave dangling resources they will be cleaned up for you by the kernel. There may be a few exceptions, but Mach ports (which is what IOKit handles are) are not one of them. I thought as much, but it seems strange to me that in this case, the computer will no longer go to sleep due to being idle. I've tested it with a simple terminal program. If I interrupt the run loop (^C for example or SIGTERM) and don't call IODeregisterForSystemPower() the computer simply will not sleep again until it's been rebooted. If anyone else could test this, I'd really appreciate it... it seems like a bug but I only have my hardware at the moment to test on and there may be something wrong with that.
