There's no reason to assume that NSTableView remembers the last value
it got from -numberOfRowsInTableView:. In fact, the documentation
indicates that NSTableView does in fact ask for this information very
frequently; not being privy to the internal details, I wouldn't be
surprised if NSTableView asks for the number of rows every time it
redraws.
