+# amazoncorretto:26 and :27 images, and python3. Takes roughly 15-20 minutes, most of it the G1 cost runs.

+# Non-deterministic outputs (timings, RSS, GC counts, the machine's preferred SIMD species) will differ on your
+# machine; the shape should not. Everything else is byte-stable between runs.
