Previously we unmapped and re-mapped if restoring from a checkpoint. However, we never checked that the new mapping was actually the same, it was just magically working as the OS seems to fairly reliably give us the same chunk back. This patch fixes this issue by relying entirely on the mmap call in the constructor. |
