The current size may be bigger than the correct one, this needs to be
revisited later.
I don't believe this is true anymore. When this was written initially CNL had a higher value.
Higher values are ok, but smaller can be problematic if I understood correctly.
So we might need to check the accurate number.
Oscar has a good method for that if iirc ;)
My method says 14 pages. Seems a bit low, so I went ahead and tested it.
Everything seems to work fine, so I'll send a new patch.
v2: Rebase.
