A, B
  A is the trace named first, B the one given to --compare.
  pauses                collections gcmon recorded, over every run.
  gc                    run time in the collector, from the target's cumulative counter.
  cov                   the pauses gcmon recorded, summed, over `gc`. Below 100% the trace
                        missed collections, and every column to the right is over the ones it
                        kept.
  share                 each run's `gc` over its own length: pyperf's timing where a results
                        file sits beside the trace, the `Lifetime` span otherwise.
  gap                   the median run's median interval from one collection ending to the next
                        beginning, inside one interpreter. The pacing: half the `gap` is the
                        collector running twice as often. Where `cov` is short the gaps hold the
                        collections the trace missed.
  per pause (ms), P99   the median run's 99th percentile.
  per pause (ms), max   the median run's longest pause.
  collected (obj), P99  the median run's 99th percentile of the objects one collection freed,
                        over the collections whose own counts the trace holds.
  collected (obj), max  the median run's largest of those.
  empty                 the median run's collections that freed nothing, over the collections
                        whose own counts the trace holds.

delta on gc
  B/A                   the ratio as a multiplier: `÷1.51` where B is the smaller, `x2.34` where
                        B is the larger. The GEOMEAN row takes the same form.
  margin                `B/A` over the run-to-run noise, as a multiple: above 1 the difference
                        is outside the noise, below 1 inside it. The noise is the 95% half-width
                        of a bootstrap: each side's runs drawn again with replacement and the
                        row's metric rebuilt from the draw.

  Loops                 both counts on the 5 of 119 rows where the sides calibrated --loops
                        differently, blank where they agree. Those rows ran different amounts of
                        work.

GEOMEAN B/A
  the geometric mean of the per-row ratios, each row counted once whatever its size. `margin`
  under it is the delta column's, taken over the whole table: every row's runs drawn again at
  once and the mean rebuilt from the draw.

cycles (n)
  count       a cycle runs from `old_work` leaving zero to its return: young collections raise
              it by promoting, increments work it down. It holds every collection in between, of
              any generation.
  pauses/cyc  mean collections in a cycle.

share (%)
  grace       collections before `old_work` first reached zero, from the -100000 an interpreter
              starts at. Only the three counts include them.
  done        cycles ended by the pending space emptying.
  full        cycles ended by a full collection.
  lost        cycles ended by a record gcmon missed. The rest ran to the end of the trace.
  skip        `middle` collections that did no old-space work.
  coast       collections of any generation that inherited `old_work` below zero.
  paid        increment work done over the debt the cycles reached, both summed over the cycles.
              Below 100% the increments left debt standing, above it they overshot.

idle (n)
  runs of consecutive collections with `old_work` below zero.

timing (ms)
  Medians.
  cycle       the first collection's start to the last one's end.
  gap in      one collection ending to the next beginning, inside a cycle.
  gap out     a cycle ending to the next beginning, across a real reset only.
  worked      a `middle` collection that did old-space work.

heap (obj)
  Means.
  in          how many tracked objects the heap gained between two collections of a cycle:
              `heap_size_stop` to the next `heap_size`. Negative where the mutator freed more
              than it created between them.
  out         the same across a cycle boundary.
