  You aren't using the same CGContext from several threads, are you? 
That's unsupported. You have to create a new CGContext (or 
NSGraphicsContext) for every thread you draw from.

  If that's not what you're doing, I have no idea, but statistics 
says it's probably something similar, that you're using something 
from two threads you shouldn't, or releasing an object in one thread 
that's still used in another.
