Good point. I've never seen it in my samples, so it would be interesting to know what triggers it (and I even downloaded TeXShop to sample it!). That thread is also blocking, and not doing any work, so it's certainly not burning up anything. Running nm and otool, TeXShop is not linked with the OpenGL framework or calling any gl functions, but I did notice some transient Core Animation threads.
