Martin, that problem seems to go away when I initialize $res to 0 in 
_fetchfile. 

I don't know perl, and maybe local variables are pre-initialized to empty. 

When a new file that is empty is created, sub _line would call
sub _fetchfile with $cnt == 0, and it can return $res which
is initialized to 'undef'.  That explains why sub file says
$self->_line() returned an undef and I think what you did is the
right fix.
