* The main isolate spawns two isolates: isolate1 (with entry point

* 'crossIsolate1') and isolate2 (with entry point 'crossIsolate2').
|
|
*
|
|
* The main isolate creates two isolates, isolate1 and isolate2.
|
|
* The second isolate is created with a send-port being listened on by
|
|
* isolate1. A message is passed along this from isolate2 to isolate1.
|
|
* Isolate1 then sends the result back to the main isolate for final checking.
