Is UIGraphicsBeginImageContext thread safe?

Question

So I\'ve been under the impression that UIGraphicsBeginImageContext is thread safe, and can be called from any thread to create a new CGContextRef that can be used to draw.

Answer 1

To quote from the documentation:

In iOS 4 and later, you may call this function from any thread of your app.
