/**
 * The Jest farm (publicly called "Worker") is a class that allows you to queue
 * methods across multiple child processes, in order to parallelize work. This
 * is done by providing an absolute path to a module that will be loaded on each
 * of the child processes, and bridged to the main process.
 *
 * Bridged methods are specified by using the "exposedMethods" property of the
 * "options" object. This is an array of strings, where each of them corresponds
 * to the exported name in the loaded module.
 *
 * You can also control the amount of workers by using the "numWorkers" property
 * of the "options" object, and the settings passed to fork the process through
 * the "forkOptions" property. The amount of workers defaults to the amount of
 * CPUS minus one.
 *
 * Queueing calls can be done in two ways:
 *   - Standard method: calls will be redirected to the first available worker,
 *     so they will get executed as soon as they can.
 *
 *   - Sticky method: if a "computeWorkerKey" method is provided within the
 *     config, the resulting string of this method will be used as a key.
 *     Every time this key is returned, it is guaranteed that your job will be
 *     processed by the same worker. This is specially useful if your workers
 *     are caching results.
