So I have an application that has been bedeviled by a nasty, nasty

Error (1007) creating CGSWindow
At that point, the user has no choice but to reboot the machine -
the Window Server is pretty much hoarked.
You have too many cached NSImages. Because NSImage uses windows to
cache images, and because these windows are a system wide resource
managed by the Window Server, eventually it can no longer create new
windows in any process. The work around is to use Core Graphics
directly, which doesn't suffer from this problem.
