    SubjectRe: Kaffeine problem with CFS

    hm. I've reviewed all uses of demux_lock. ./src/xine-engine/demux.c does
    this:

    pthread_mutex_unlock( &stream->demux_lock );

    lprintf ("sched_yield\n");

    sched_yield();
    pthread_mutex_lock( &stream->demux_lock );

    why is this done? CFS has definitely changed the yield implementation so
    there could be some connection.

    OTOH, in the 'hung' state none of the straces suggests any yield() call.
