Comment:

 After I'm given your comments, I've realized as the followings. Is this
 correct?

 - We may implement an abstract counter class under isc.statistics.
 - We shouldn't implement a concrete counter class, e.g.
 ``!XfroutCounter``, for a specific module under isc.statistics.
 - We may implement such a concrete counter class in the module, e.g.
 ``b10-xfrout.py``, which uses it.
 - We should complete implementation of an abstract counter class like
 #2300 in advance.

 If correct, I'd like to restart from the fourth one.
