Don't think you'd need to fully copy it - you can just have a "wrapper" memory context implementation that does the accounting and then hands the actual work to AllocSet. That limits some things it can account for, but I don't see those being really relevant. > I wonder if an aggregate might use a custom context > internally (I don't recall anything like that).
