What happens on timeout?  Do we just let userspace continue polling

the file descriptor, and then ignore the notification?

Then in fact the notification could just become the reply:
<- POLL-request (sent with request_send_nowait())

...

-> POLL-reply  (calls req->end())
So there won't even be a need to implement notification (we'll need

that for other things in the future) simplifying things even further.

Even if we want to cancel the request because of a timeout, that could

be done with the existing INTERRUPT request.
