The benchmark was not progressing for 1.5 hours.

It doesn't hang, it just takes realllllyyy long time due to how slow zopfli is and how many iterations cargo has to make to get reasonably precise results. I left it overnight and it has finished successfully.

Yeah, this probably does require some tuning, and maybe moving to something like Criterion for benchmarks would also help here.
