310 Apart from this size requirement, a checkpoint transaction looks no different
313 perspective, the checkpoint transaction is also no different - just a lot
317 Because the checkpoint is just another transaction and all the changes to log
320 minimise the time we hold the CIL locked while writing the checkpoint
324 per-checkpoint context that travels through the log write process through to
325 checkpoint completion.
327 Hence a checkpoint has a context that tracks the state of the current
