   FWIW, I think the code that calls this cleanup is making too many assumptions about how the allocator is used. Specifically, it assumes that we can know, for a fact, that we were the last ones to use it, even though we share it with C library code, whose implementations we cannot know for certain. Refactoring to avoid this assumption would be good, I think.
