// and expect epoll to no longer return events for the descriptor, as
// all the pipe ends should be closed by then (the child is dead, so its
// pipe FDs have been closed [assuming it hasn't forked without closing
// the descriptors, which would be evil], and we would have closed all
// of our FDs for this pipe as well). In practice that doesn't work.
