reloadData calls setNeedsDisplay:YES, and setNeedsDisplay: just marks
the view as needing to be displayed. The actual display operation
occurs at the next run loop iteration.

You can try to force immediate display by using display instead of
setNeedsDisplay:YES. But the best solution would be to have a second
thread compute the thumbnails and notify the main thread each time a
new thumbnail is available. This would enable the user to continue
using your application while thumbnails are being generated.

However, you will have to enable your model classes for multithreading
(by adding locks).
