/*
 * The goal of this test is to cover the Workers' implementation of
 * Worker.prototype.destroy. Worker.prototype.destroy is called within
 * the worker's context: once when the worker is still connected to the
 * master, and another time when it's not connected to it, so that we cover
 * both code paths.
