Sometimes crashes the host app #2

This is probably a bug in my CF memory management. Or it could be that I need to add locks / mutexes somewhere. The stack trace doesn't show the apps crashing inside my code however so I think it's most likely memory management.

So there was this impossible undocumented quirk where you need to retain the clock every time you return it (but not other memory managed objects). I wish Apple would just tell you this kind of thing in their docs.

But it's fixed now :tada:

I like how you speak about "this one" undocumented quirk. This whole thing is an undocumented mess :D
