I seem to recall that you have to call mach_port_deallocate() for any port returned from mach_thread_self()...Are you doing that? No one should be using mach_thread_self(), unless you are creating raw mach threads. Use pthread_mach_thread_np() instead. This does not require a mach_port_deallocate(). I believe the port leak being seen here is normal, as a thread port remains after the thread is detached, to be cleaned up by the next pthread_create() or pthread_exit() that is called.
