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();
`----
