 * Thread utilities built on thread_spawn() and thread_join().

 * Methods:
 *   spawn(func, args) -> thread id number (args may be a single value or an array of values)
 *   join(id) -> returns the thread function's return value
 *
 * Convenience aliases:
 *   start(func, args) -> same as spawn()
 *   wait(id) -> same as join()
