This change isn't really necessary (although it doesn't hurt anything). Nothing is being asserted in the callback, so the test should fail if it's not called.

const worker = cluster.fork();
worker.on('exit', common.mustCall(function(code, signal) {
assert.strictEqual(code, 0, 'Worker exited with an error code');
assert.strictEqual(signal, null);

You could have left the 'Worker exited by a signal' as the third argument here.

This bug was in the original test, but the next line will never execute because common.fail() (and, in the existing test, assert(false, ...)) result in the termination of the program.

Maybe @cjihrig @mcollina or @bnoordhuis can give this a quick review? (Looping in the people suggested for cluster stuff in onboarding-extras.md.)
