Generally though, sometimes our use of OMP_NUM_THREADS makes other systems sad. It's unfortunately somewhat difficult to turn off. A common approach is that people set `OMP_NUM_THREADS=""` but this doesn't properly unset things. I'm curious if an approach like this would be helpful. There might be a cleaner way to do this, and this might be a bad idea. Please feel free to reject. It was just easy to put this up as a PR.
Not anytime soon but seems like a positive change to me. |

No objections. It appears to not be working, though. The test is failing (linter is also off) |
