Based on our understanding of the failure, this can be changed back to being
non-refcounted.

I imagine you don't have time to make that change before losing access on
Friday, so feel free to leave this as-is and just add a TODO:

TODO(eroman): no need for this to be RefCounted.

No need for this to be virtual.

Remove this comment.

The problem as described in earlier comment was function argument evaluation
order difference between Windows compiler, and is easily solved.
