No, I don't think so? Given that we currently use `size` in heapwords as size in bytes, we always get to resizing code with _smaller_ value. So I think the "worst case" is that allocation code would loop through expansion multiple times before `par_allocate` would finally complete, or we figure there is not enough space.
