Called upon exit from the context manager.  Implements the
debugging output.

:param exc_type: The exception type.  If no exception was
                 generated, will be ``None``.
:param exc_value: The exception value.  If no exception was
                  generated, will be ``None``.
:param exc_tb: The exception traceback.  If no exception was
               generated, will be ``None``.

:returns: A ``True`` value if any exception should be ignored,
          ``False`` otherwise.  Will return ``True`` for all
          ``Exception`` subclasses unless debugging is
          enabled.
