Research direction
Start with TestFoundation/TestNSURLSession.swift, especially the test at line 254, and run TestURLSession.test_downloadTaskWithURLAndHandler to reproduce the timeout. Trace the asynchronous expectation and download task behavior; done means the test no longer intermittently exceeds its 12-second timeout.
