I guess that the debug printing would go out of hand as well, 970
characters printed into the console is no fun either. The test needs a
bit more than just bumping the number of pages. However as we are
getting really close to release I guess that the best course of action
would be workarounding the issue for now by bumping the number of pages
to something as 128 pages. Then we can rework the test once LTP has been
released.
