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

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.
