jackd is a 100% synchronous design,  entirely by intent.

Thanks Paul! I was time stamping the output of audio codec  decoded PCM
samples which was introducing lot of jitter. Now I'm reusing what Fons had
implemented on zita-j2a using a *local* fifo and not the buffers which used
to connect the graph. I need to test the control loop for my audio app.

btw,  is it possible to send some asynchronous control signals in jackd ?
