-/*
- * Everything starts in the main-isolate (in the main-method).
- * The main isolate spawns two isolates: isolate1 (with entry point
- * 'crossIsolate1') and isolate2 (with entry point 'crossIsolate2').
- *
- * The main-isolate creates a new message-box and sends its sink to both
- * isolates. Whenever isolate1 or isolate2 send something to the main-isolate
- * they will use this sink.
- * Isolate2 stores the sink and replies with a new sink (sink2b) it created.
- * Isolate1 stores the sink and waits for another message.
- * Main receives isolate2's sink2b and sends it to isolate1.
- * Isolate1 stores this sink as "otherIsolate" and send a new sink (sink1b) to
- * the main isolate.
- * Main receives sink1b and sents a message "fromMain, 42" to sink1b.
- * isolate1 receives this message, modifies it (adding 58 to 42) and forwards
- * it to isolate2 (otherIsolate).
- * isolate2 receives the message, modifies it (adding 399), and sends it to
- * the main isolate.
- * The main-isolate receives it, verifies that the result is 499 and ends the
- * test.
