In my experience, CoreImage is not thread safe. I could probably dig up the details if necessary, but the gist is that we were experiencing CoreImage-related crashes when running off the main thread. Moving to the main thread fixed the crashes.
Unfortunately, I'm not aware of any documentation regarding CoreImage thread safety.
