Sorry, the destructor has to, of course, be used in a safe manner - I didn't mean to imply otherwise. Given what `free_metadata` does with the `md` we can't call the destructor before calling it. Perhaps we can add a default parameter `bool invoke_destructor = false` to `free_metadata`, to then call the destructor at the right point (which would be before or after `md->deallocate_contents`).
