So my task list is:
0) Rebase against the HEAD that just code related to this touched today
1) Assume that log_checkpoints is sufficient control over whether the
timing overhead added is worth collecting, and therefore remove the
half-baked idea of also wrapping with a compile-time option.
2) Have the sync summary returned upwards, so it can be put onto the
same line as the rest of the rest of the log_checkpoint info.
All seems reasonable to me. Will rev a new patch by tomorrow.
