| /// @assertion Spawning an isolate is accomplished via what is syntactically |
| /// an ordinary library call, invoking one of the functions spawnUri() or |
| /// spawn() defined in the dart:isolate library. |
| /// However, such calls have the semantic effect of creating a new isolate |
| /// with its own memory and thread of control. |
| /// @description Checks that a new isolate created with spawn() has its own |
| /// memory which is not shared with other isolates, using a top-level variable |
| /// to showcase it. |
