What is the circular reference problem?  I don't remember hearing we had 
one?

that part defines a DESTROY method in that package

and that part runs the code in Logger.pm, which includes

	__PACKAGE__->reset();

which includes

	$ROOT_LOGGER = __PACKAGE__->_new("", $DEBUG);

and that $ROOT_LOGGER object is what then gets DESTROY'd.


That was too easy.  Is this a trick question?
