By "dumping", do you mean discarding the data? If so, wouldn't it work
if you would call pa_stream_read() on "Reset" and just throw away that
data? That way the client-side buffer would be emptied. You could call
pa_stream_flush() prior to that, if you think flushing also the
server-side data is in some way useful.
