12447: Reduce memory footprint of crunch-run.

  • BlockCache reads into a fixed-capacity buffer, to avoid reallocations (this
    cuts resident memory usage by 1/2 and makes memory footprint extremely
    stable)
  • Limit the crunch-run BlockCache to 2 blocks instead of 4 (cuts footprint by
    1/2 again)
  • Clear the crunch-run BlockCache after loading the Docker image (probably cuts
    post-image-load footprint by 1/2 again).
