Hmm, I see.

Well yes, but doesn't the SD server do this.  AIUI the library we
link to implements a client.  In any case, I think you might be right.

I just turned on autospeak and tried a few times to press a routing key
during speech output and after the third or fourth try I managed
to completely hang brltty.  I again got the routing start sound but
nothing else, but this time my display hung and nothing reacted.
This is a new phenomenon, but might be the same source.  I still wonder how it
can happen without me using autospeak, I wasn't using speech at all.
