      Valgrind flagged some uninitialized memory being written during a checkpoint.

      When setting up a checkpoint, we leave room in the buffer for a packed uint64_t to be inserted later, and the packed uint64_t doesn't necessarily require all the space we allocate for it, and the remaining bytes were left uninitialized.
