Invoke the ExtendableEvent's `waitUntil` method in order to discourage user agents from terminating service workers while asynchronous tests are running (which would interfere with test execution). Although the user agent is still free to terminate workers when execution "exceeds imposed time limits," this precaution should prevent interference for the most common cases. > # 2.1.1.
