* @assertion Future<Isolate> spawn(void entryPoint(message), message,
* {bool paused: false, bool errorsAreFatal, SendPort onExit, SendPort onError})
* The argument entryPoint specifies the entry point of the spawned isolate.
* It must be a top-level function or a static method that takes one argument -
* that is, one-parameter functions that can be compile-time constant function
* values. It is not allowed to pass the value of function expressions or
* an instance method extracted from an object.
* The entry-point function is invoked with the initial message. Usually
* the initial message contains a SendPort so that the spawner and spawnee can
* communicate with each other.
* @description Checks that an isolate can be spawned from a newly spawned
* isolate.
