Seems like IBM i has the same issue as SmartOS and will most likely need the same conditional

node/test/fixtures/spawn-worker-with-copied-env.js

Lines 4 to 7 in 3a5b542

	const assert = require('assert');
	if (process.platform !== 'sunos') { // --title is unsupported on SmartOS.
	assert.strictEqual(process.title, 'foo');
	}
