Your concern is that we can still call get on the derived class between the 
derived and parent destructor runs. You're right - we should remove as the 
first step in the destructor of the derived class.

I don't know of a good way to enforce it other than checking in the base 
(Metric) destructor that the metric has been removed. I'm open to alternatives.
