   No! i didn't say there is a busy loop involved here.

   Your understanding is quite correct IMHO. As i said, you have most
probably found a bug, either in gstreamer or dsp plugins, although i
doubt this is a gstreamer bug. So file a bug against the dsp plugins,
it will flow upstream if need be.

    AFAIK, yes.
