I looked at your patch.  Basically, you kill Speech Dispatcher if one of
the output modules stops.
That certainly solves the problem.  Maybe it would be nice if SD could
gracefully switch to a new module or restart the one that
stopped.  But what you have here is good enough for me.  If there are no
objections, I'll push it for you.
