 *     Creates and spawns an isolate that runs the code from the library with
 *  the specified URI.
 *     The isolate starts executing the top-level main function of the library
 *  with the given URI.
 *     The target main must be callable with zero, one or two arguments.
 *  Examples:
 *   main()
 *   main(args)
 *   main(args, message)
 *     When present, the parameter args is set to the provided args list. When
 *  present, the parameter message is set to the initial message.
 *
 * @description Checks that an isolate can be spawned from a newly spawned
 * isolate.
