... via _NIX_TEST_NO_ENVIRONMENT_WARNINGS This environment variable suppresses warnings that depend on the test environment (such as ulimit warnings in builds on systems with lower limits, which may well succeed if it weren't for the warning). This prevents non-deterministic test failures in golden/characterization tests. Alternative considered: filtering stderr in test scripts, but that approach is fragile with binary test output, and potentially multiple call sites.
