Hmm this shouldn't be the case:

- The primary changes will release the memory less often, so there shouldn't be an impact on runtime.
- The packed counter array size change is a bug that would make us use the static buffer less often, so we are saving some mmap calls there.
- The clear() addition to the batch pre-destroying only matters when trying to reclaim transfer batches which happens only on a forced release.
