   Peak `MemoryPool` reservation per query β€” what DataFusion's accounting 
believes it reserved. Recorded only for benchmarks that write a results JSON 
(the `dfbench` suites, and the suites `bench.sh` runs through the Criterion SQL 
harness since apache/datafusion#25644), and only under a memory limit: 
`DATAFUSION_RUNTIME_MEMORY_LIMIT`, or one the suite sets itself.

   **Pool accounting vs. process RSS**
   
   Max pool peak is the largest reservation any single query in the run 
reached; peak RSS covers the whole invocation, including data loading and 
allocator retention, and the two high-water marks need not coincide in time. 
The gap is therefore an upper bound on what the pool did not account for, not a 
measurement of it.
