I think we can skip sigwait() too since the thread will exit when done. Then any pending signals are presumably dropped. (I suppose some OS could give them to another thread, but that goes against delivering them to a particular thread like SIGPIPE is.)

That's what my initial patch did. At least on OS X this leads to the process receiving SIGPIPE and dying. I can attach a test case as well if desired.
