[NSImage lockFocus] most definitely crashes on 10.5 when called from a secondary thread. I have dozens of crash reports from users verifying the problem.

I was unable to reproduce the problem in a small test application, though, so the problem is more complicated than just that one call. My work-around was to do all NSImage related work on the main thread, which is ok in our case but definitely sub-optimal in others.
