What happens if you remove the isCancelled checks?
How do you create your operation queue?
What is the max concurrent operation count of the queue? If
NSOperationQueueDefaultMaxConcurrentOperationCount, what happens if you set it
to (processorCount) instead?

No effect on blocking.

By the way, it's worth pointing out that NSOperationQueue is NOT a thin
veneer around GCD.

On Oct 25th 2012 I posted about this.
I finally got around to digging into what the cause was and have now got my app
working correctly (or at least the way I want it to).
In summary it was all related to saving and restoring the graphic context
correctly in -drawRect.
In my case I use a

My app is a Document app and I implemented -(void)makeWindowControllers.
It could have several documents open at the same time.
In particular I want to cascade the window when a New document is opened.
I've read up on this and am aware of the NSWindow method

The document architecture already provides proper cascading behaviour. What are
you seeing that makes you think you need to implement it yourself instead?

Using Xcode, it appears that UIImage is for iOS (this is just a
supposition). So XCode changes the code to CIImage.
