OK; I was thinking of both the object qname and its module's qname,
but I agree that they are separable.

I would personally be satisfied with just timing the regression suite

representative workloads.

My biggest concern is that any memory increase (let alone 6%) may
matter if it forces the use of extra cache lines.
