The task
After a process customises the slack (e.g., a latency‑sensitive thread sets it to 0 or a power‑saving daemon increases it) and is then checkpointed and restored, the value silently reverts to the default. This silently breaks application behaviour because the threads no longer behave as they did before the checkpoint.
