No, you only do it if isatty() says that this is a tty device, but the
tty device doesn't know what size it should be (returns 0,0).

In any case, the size querying logic should handle this for you
automatically (eventually), the comment was just about not calling it
_too_ frequently, which probably isn't an issue here.
