> Tests take a long time. Our fork count running all tests are conservative -- 1 (small) for first part and 5 for second part (medium and large). Rather than hardcoding we should set the fork count to be relative to machine size. Suggestion here is 0.75C where C is CPU count. This ups the CPU use on my box.
> Looking up at jenkins, it seems like the boxes are 24 cores... at least going by my random survey. The load reported on a few seems low though this not representative (looking at machine/uptime).
> More parallelism willl probably mean more test failure. Let me take a look see.
