Please ignore this paragraph.  Actually if that happens, we'll queue
the response onto the response queue as usual, then as long as the
output channel is not closed it'll still be delivered to the
filter_output process.

So I think I agree with Markus's solution, we just flush the response
queue when we get CLOSED (but we don't close the output fd; IMHO
that's chardev backend's job).  Would that work?
