As far as I can tell, that program isn't multi-threaded, and it should
not have returned to user land at all (no signal, and a restart). So I
think it's a kernel-only thing - there should have been nothing that
could have changed the poll list in user space. But I didn't really
check the threading status.

I'm trying to bisect it now to figure out more hints.
