If you have a small test app, can you please raise the bug with bug-
reporter. In practice the kernel does usually clean up after a mach-
port de-register but you could have detected a corner case.
Thanks

No matter how your app terminates, if you leave dangling resources

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.
