It looks like NSUIHeartBeat could be attempting to lock something.
Although I could be wrong, it may not be related.
Here's the full stack trace across all threads.

You could also show any other thread stuck trying to lock a mutex? I

Hi,
I'm currently trying to track down a deadlock. After adding a
series of layers, CoreAnimation deadlocks here on the main thread:

There are a bunch of other threads, too many to reasonably list in
a message to the list.
While I continue debugging and trying to track down what I'm doing
that starts the deadlock, does anyone have any general ideas on
where it would be best to look?
Thanks,
Colin
