   Process output is distributed to filters when Emacs has nothing else
   to do, such as when pausing for interaction (‘read-string’ et al).
   (You can also explicitly request it via ‘accept-process-output’ but
   that is not germane.)

   So the best strategy is to not allow such pauses in the first place.
   E.g., you could add an abstraction ‘start-filtered-process’ and make
   sure you use ‘start-filtered-process’ everywhere you'd normally use
   a naked ‘start-process’.

I see, Thanks.  It looks like a bug or shortcoming, though.  I was
expecting the sequence to be similar to this:

,----
| Filter *filter = new Filter;
| Process *proc = new Process(filter);
| proc->start();
`----
