| * @assertion Stream errors |
| * Returns a broadcast stream of uncaught errors from the isolate. |
| * Each error is provided as an error event on the stream. |
| * The actual error object and stackTraces will not necessarily be the same |
| * object types as in the actual isolate, but they will always have the same |
| * Object.toString result. |
| * This stream is based on addErrorListener and removeErrorListener. |
| * |
| * @description check that several subscriptions to the errors stream is |
| * possible. |
