Constructors without additional constraints execute in somewhat arbitrary order.  Destructors, in the C++ sense, do not. Their execution order is the reverse of the arbitrary constructor call order, i.e. exactly fixed.

However that does not detract from this patch looking like the right thing. Thank you for changing the commit message to better correlate with the existing implementation.
