I also had a second idea, barely good enough to mention and probably just paranoia. In a nearby thread I learned that process exit does not release Windows advisory file locks synchronously, which surprised this Unix hacker; it made me wonder what else might be released lazily after process exit. Handles?! However, as previously mentioned, it's possible that even with fully Unix-like resource cleanup on process exit, we could be confused if we are using "the process that was on the end of this pipe has closed it" as a proxy for "the process is gone, *all* its handles are closed". In any case, the previous kluge should help wallpaper over any of that too, for this test anyway.
