To be completely clear about this, these leaked ports are not

Mach will clean them up for you at task termination. However,
whenever you don't need the resource, you should do the proper
thing to release it.
Thank you for the clarification. It seems to me that the example
should be changed to simply _exit(2) since the ports will be
cleaned up.
The problem is that someone will copy the example into a library
routine and replace the _exit() with a return. Then they wonder
why they leak - since Apple provided the example and it should have
managed its resources.
That's a good point. Maybe the signal handler could be changed (and
maybe catch SIGQUIT as well) to stop the run loop and then clean up
after the run loop has terminated. But then, that might just confuse
the issue.
Actually, a comment just after the run loop would probably be best
saying that in actual use the clean up code needs to be called.
