Re: Kaffeine problem with CFS

[Ingo Molnar]

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.
