> time: 68488258 ns.
> {noformat}
> I'm not sure if there's a case when elapsed time in nanoseconds is meaningful
> for these background chores, but we could do a little work before printing
> the number and time unit to truncate precision down to something a little
> more intuitive for operators. This number purports to be an average, so a
> high level of precision isn't necessarily meaningful.
> Separately, or while we're here, if we think an operator really cares about
> the performance of this chore, we should print a histogram of elapsed times,
> rather than an opaque average.
