The identified CL cannot have been responsible for this memory change.

Back to kraynov to see if a more appropriate regression range can be found.

=== BISECT JOB RESULTS ===
Perf regression found but unable to narrow commit range

Build failures prevented the bisect from narrowing the range further.
