Good obervation Erik, although I get the same result with heightOfRow
set to 500 and 1, the critical point is still 63632 rows.

I have not verified it, but doing the math in my head, 63632 * 160
seems just large enough that it can not be completely represented
in a 32 floating point type. At a minimum, I would expect display
glitches when you create a table view that is more than 10 million
Postscript points tall. That would after all only require 14
thousand pages to print on 8.5x11 inch paper assuming 10 useful
inches per page...
Anyway, perhaps some dangerous casting is going on somewhere
(possibly even in the frameworks), and a table that tall results in
an address calculation with a negative offset or something else
unsafe.
