Research direction
Start by reproducing the behavior with pytest 3.6.0, pytest-xdist 1.22.2, 120 tests, -n20, and the reported --dist modes. Inspect pytest-xdist's worker scheduling behavior and compare the run with the screenshot. Done means determining whether idle workers are expected or identifying a reproducible scheduling bug with a clear expected result.
