 connor (he/him) | wanting to figure out the cost of evaluating a single attribute led me to make https://github.com/ConnorBaker/nix-eval-jobs-python | 06:06:20 |

| hexa | stuck at 22% | 23:30:09 |
| hexa | I recommend finding a machine to reproduce, then going in with pytestFlagsArray = [ "-vvv"] and possibly pytest-timeout | 23:30:39 |
