            return POE::Session->new(

            );
        },

=head1 DESCRIPTION

This is a factory object that creates L<POE::Component::Supervisor::Handle::Session> objects.

=head1 ATTRIBUTES

See also L<POE::Component::Supervisor::Handle::Session/ATTRIBUTES>, all of the
documented attributes that apply to handle creation are borrowed by this class.

=over 4

=item handle_class

The class to instantiate.

Defaults to L<POE::Component::Supervisor::Handle::Session>.

Note that attributes are inherited only from
L<POE::Component::Supervisor::Handle::Session>. If your handle class requires
additional attributes, you must subclass your own C<Supervised> variant.

The C<_inherit_attributes_from_handle_class> method can then be invoked on your
subclass to re-inherit all the attributes. Read the source of
L<POE::Component::Supervisor::Supervised> for more details.

process should be spawned.

=item is_abnormal_exit

Used by C<should_restart>. See L<POE::Component::Supervisor::Supervised> for
details.

Returns true if the C<error> argument is provided (it's added by the handle
when a C<DIE> signal is caught from one of the tracked sessions).
